The Waking State is another Dream | Shankara, Gaudapada, Upanishads | Advaita Vedanta | Sri Ramana Maharshi

Here we will see, using quotes from Gaudapada, Shankara, the Upanishads and Sri Ramana Maharshi that the same essential teaching is taught regarding the reality of the waking and dream states – namely that they are both equally unreal, that both waking and dream are dream!


Tom: Here is verse 1 from chapter 2 of Gaudapada’s Mandukya Karika (Gaudapada’s four chapter commentary on the Mandukya Upanishad), my comments are in red:

2.1. Harih Aum. The wise declare the unreality of all entities seen in dreams, because they are located within the body and the space therein is confined.

Tom: Gaudapada is essentially stating something we already know, namely that we dream of many things, but all these things we dream of are not actually real. They are all projections of the mind, which is what Gaudapa means by ‘located within the body and the space therein is confined’

2.2. The dreamer, on account of the shortness of the time involved, cannot go out of the body and see the dream objects. Nor does he, when awakened, find himself in the places seen in the dream.

Tom: Again, Gaudapada is stating what we already know about dreams. Shankara in his commentary on this verse explains this means that if we dream of going to a far away land many hundreds of miles away that would take several months to travel to, there is not enough time in dream, which only lasts a few hours, to actually travel there. Similarly, when we wake from the dream, we do not find ourself in this dream location far away.

2.3. Scripture, on rational grounds, declares the non-existence of the chariots etc. perceived in dreams. Therefore the wise say that the unreality established by reason is proclaimed by scripture.

Tom: Gaudapada in verses 2.1 and 2.2 has shown that the many things perceived in dreams are not real on the basis of our own experience. Now he is stating the same based on scripture, referring to Brihadaranyaka Upanishad 4.3.10, which states, referring to a dream about chariots:

‘There are no chariots, nor animals to be yoked to them, nor roads there, but he creates the chariots, animals and roads. There are no pleasures, joys, or delights there, but he creates the pleasures, joys and delights. There are no pools, tanks, or rivers there, but he creates the pools, tanks and rivers. For he is the agent’.

The idea from Gaudapada is that if we dream of a chariot, that chariot is not real, as confirmed by scripture. Note that the teaching that is given in the next two verses is essentially the same as the teaching given in Brihadaranyaka Upanishad 4.3 (please see this link for more).

2.4. The different objects seen in the confined space of dreams are unreal on account of their being perceived. For the same reason, ie. on account of their being perceived, the objects seen in the waking state are also unreal. The same condition ie. the state of being perceived exists in both waking and dreaming. The only difference is the limitation of space associated with dream objects.

Tom: Gaudapada is now equating the dream and waking states, stating that just as dream objects are perceived but not real, the same is with the waking state objects – they are also perceived yet utterly unreal. Does this mean we are to consider the waking state as unreal as a dream? The answer is yes, let us see:

2.5. Thoughtful persons speak of the sameness of the waking and dream states on account of the similarity of the objects perceived in both states on the grounds already mentioned.

Tom: The translation used thus far is that of Swami Nikhilanananda of the Ramakrishna Order. Swami Gambhirananda, also of the Ramakrishna Order, translates the last line of verse 2.5 as the wise say that the dream and the waking states are one.


In his commentary on Gaudapada Karika verse 2.5 (above) Shankara states ‘…therefore discriminating people speak of the sameness of the states of waking and dream.

We can see that Gaudapada and Shankara are both explicitly stating that the waking state is another form of the dream state, and whilst we often distinguish between waking and sleep, they are actually both dream states, and all that is perceived within waking and dream are equally unreal.

Again, note that this teaching is also given in Brihadaranyaka Upanishad 4.3

We see the same teaching given much more concisely in Shankara’s masterpiece, Vivekachudamani:

170. In dreams, when there is no actual contact with the external world, the mind alone creates the whole universe consisting of the experiencer etc. Similarly in the waking state also; there is no difference. Therefore all this (phenomenal universe) is the projection of the mind.

Tom: We can see that Shankara is saying that the mind projects both the dream state and the waking state. Note that this is essentially equating the mind with maya. Shankara goes on to reiterate this view in subsequent verses:

171. In dreamless sleep, when the mind is reduced to its causal state, there exists nothing (for the person asleep), as is evident from universal experience. Hence man’s relative existence is simply the creation of his mind, and has no objective reality.

177. The mind continually produces for the experiencer all sense-objects without exception, whether perceived as gross or fine, the differences of body, caste, order of life, and tribe, as well as the varieties of qualification, action, means and results.

Tom: Above we can see that Shankara has equated Mind with Maya. Now he will equate Mind with Ignorance. We can deduce that all three, Mind-Maya-Ignorance, are just three names for the same phenomenon:

180. Hence sages who have fathomed its secret have designated the mind as Avidya or ignorance, by which alone the universe is moved to and fro, like masses of clouds by the wind.

Sri Ramana Maharshi

Like Shankara and Gaudapada, Sri Ramana also equates ignorance and maya, and he further says the same phenomenon is also called ego, jiva, conceit, and impurity – ie. all these various words mean the same thing, and that this ignorance is essentially the ‘I am the body idea’ – see here, taken from the text Vichara Sangraham (Self-Enquiry) in the answer to question 3:

Sri Ramana Maharshi:…Therefore, the ‘I-consciousness’ which at first arises in respect of the body is referred to variously as self-conceit (tarbodham), egoity (ahankara), nescience (avidya), maya, impurity (mala), and individual soul (jiva).

In question 10 of the same text, Vichara Sangraham (Self Enquiry), Sri Ramana says the following:

Question: If the entire universe is of the form of mind, then does it not follow that the universe is an illusion? If that be the case, why is the creation of the universe mentioned in the Vedas?

Sri Ramana Maharshi: There is no doubt whatsoever that the universe is the merest illusion. The principal purport of the Vedas is to make known the true Brahman, after showing the apparent universe to be false. It is for this purpose that the Vedas admit thecreation of the world and not for any other reason…this world arose like a dream on account of one’s own thoughts induced by the defect of not knowing oneself as the SelfThat the world is illusory, everyone can directly know in the state of Realisation which is in the form of experience of one’s bliss-nature.

In the text Nan Yar? (Who Am I?), Sri Ramana writes:

Sri Ramana Maharshi:…The world should be considered like a dream.

Question: Is there no difference between waking and dream?

Sri Ramana Maharshi: Waking is long and a dream short; other than this there is no difference. Just as waking happenings seem real while awake, so do those in a dream while dreaming.

So, what now? Now we must put the teachings into practice to realise the truth of them:

Advaita Vedanta: Gaudapada’s Method (Mandukya Upanishad Karika)

Deep sleep is Brahman – the three states according to the Birhadaranyaka Upanishad with commentary by Shankara

(I’ve just typed this up quite quickly so, as usual, apologies for any spelling or grammatical mistakes)

The teaching of the three states (ie. the waking, dream and deep sleep states) is a staple Vedanta teaching and often the source for this teaching is cited as being the Mandukya Upanishad. However, the three states are presented and analysed in the earlier-written Brihadaranyaka Upanishad, especially in section 4.3.

Section 4 of the Brihadarankaya Upanishad consists of a conversation between King Janaka and the Sage Yajnavalkya. Now for those of you who have not encountered Sage Yajnavalkya, he is quite a character at times, demonstrating the dry humour present in many of the Upanishads. Here is an example from Section 3.1 of the Brihadaranyaka Upanishad:

3.1.1:   Om. Janaka, Emperor of Videha, performed a sacrifice in which gifts were freely distributed among the priests. Brahmin scholars from the countries of Kuru and Panchala were assembled there. Emperor Tanaka of Videha wished to know which of these brahmins was the most erudite Vedic scholar.  So he confined a thousand cows in a pen and fastened on the  horns of each ten padas of gold. 

3.1.2:    He said to them: “Venerable brahmins, let him among you who is the best Vedic scholar drive these cows home.”  None of the brahmins dared. Then Yajnavalkya said to one of  his pupils: “Dear Samsrava, drive these cows home.” He drove them away. The brahmins were furious and said: “How does he dare to call  himself the best Vedic scholar among us?” Now among them there was Asvala, the hotri priest of Emperor Janaka of Videha. He asked Yajnavalkya: “Are you indeed the  best Vedic scholar among us, O Yajnavalkya?” He replied: “I bow to the best Vedic scholar, but I just wish to  have these cows.” Thereupon the Hotri Asvala determined to question him. 

Here we have a scenario in which King Janaka effectively sets up a challenge to see who the best Vedic Scholar is, with the prize being one thousand cows. However before the challenge has even begun, Sage Yajnavalkya simply asks one of his students to take the cows. When challenged by the other scholars to see if he is really the most knowledgeable in the Vedas, Yajnavalkya dryly replies that irrespective of who the best scholar is, he just wants the cows! For me this demonstrates the humour, irony and rebellious spirit that is present throughout many of the Upanishads, but this humourous aspect of the teaching is often missed when the approach becomes overly intellectual and analytical.

Anyway, back to the three states and section 4 of the Brihadaranyaka Upanishad. In section 4.3 Yajnavalkya goes to King Janaka with the intent of not speaking, but because he had previously made a promise to King Janaka that he will answer any questions King Janaka asks, we obtain the dialogue of section 4.3 which pertains to the three states. In Shankara’s commentary on these verses he explains that the real reason Yajnavalkya visits King Janaka is to gain more wealth and cattle from the King, and throughout the following dialogue King Janaka keeps on gifting increasing numbers of cattle to Sage Yajnavalkya.

4.3.1 Yajnavalkya called on Janaka, Emperor of Videha. He said to  himself: “I will not say anything.”  But once upon a time Janaka, Emperor of Videha and  Yajnavalkya had had a talk about the Agnihotra sacrifice and  Yajnavalkya had offered him a boon. Janaka had chosen the  right to ask him any questions he wished and Yajnavalkya had  granted him the boon.  So it was the Emperor who first questioned him. 

Shankara’s commentary on the above verse reads as follows:

‘Yajnavalkya went to Janaka, Emperor of Videha. While going, he thought he would not say anything to the Emperor. The object of the visit was to get more wealth and maintain that already possessed….’

Note how this is contrary to how many nowadays state that a true teacher would not accept money or material objects for their teaching. In this, the oldest, longest and perhaps the most authoritative of Upanishads, we have the reverse situation! Again, such is the often dry humour of the Upanishads!

In the next verses, verses 4.3.2 to 4.3.6 Yajnavalkya reveals that the Self is the Ultimate Reality upon which all stands. You can see that Yajnavalkya does not give the ultimate answer straight away, but only when pressed by King Janaka does he eventually reveal the Self as the true answer he is looking for. My reading of this is that Sage Yajnavalkya only wants to give the teaching to those who are truly intererested, who are truly enquiring, and not to those who merely accept the first answer given to them:

4.3.2.    “Yajnavalkya, what serves as light for a man?”  “The light of the sun, O Emperor,” said Yajnavalkya, “for with  the sun as light he sits, goes out, works and returns.”  “Just so, Yajnavalkya.” 

4.3.3.    “When the sun has set, Yajnavalkya, what serves as light for a  man?”  “The moon serves as his light, for with the moon as light he  sits, goes out, works and returns.”  “Just so, Yajnavalkya.” 

4.3.4.    “When the sun has set and the moon has set, Yajnavalkya, what  serves as light for a man?”  “Fire serves as his light, for with fire as light he sits, goes out,  works and returns.”  “Just so, Yajnavalkya.” 

4.3.5.    “When the sun has set, Yajnavalkya and the moon has set and  the fire has gone out, what serves as light for a man?”  “Speech (sound) serves as his light, for with speech as light he  sits, goes out, works and returns. Therefore, Your Majesty,  when one cannot see even one’s own hand, yet when a sound is  uttered, one can go there.”  “Just so, Yajnavalkya.” 

4.3.6.    “When the sun has set, Yajnavalkya and the moon has set and  the fire has gone out and speech has stopped, what serves as  light for a man?”  “The self, indeed, is his light, for with the self as light he sits,  goes out, works and returns.” 

4.3.7 “What is this Self”….

In the next few verses Yajnavalkya teachings that the Self floats between two states, the dream state and waking state, but remains unaffected by theses states, returning to the state of deep sleep when not in dream or waking. All this time Yajnavalkya receives more and more cattle from King Janaka for his teachings! Here is a description of the dream state by Yajnavalkya, in which he explains the dream is a mere unreal projection:

4.3.9 and 4.3.10 ….”And when he dreams, he takes away a little of the impressions of this all-embracing world (the waking state), himself makes the body unconscious and creates a dream body in its place, revealing his own brightness by his own light-and he dreams.  In this state the person becomes self-illumined. There are no real chariots in that state, nor animals to be yoked  to them, nor roads there, but he creates the chariots, animals  and roads. There are no pleasures in that state, no joys, no  rejoicings, but he creates the pleasures, joys and rejoicings.  There are no pools in that state, no reservoirs, no rivers, but he  creates the pools, reservoirs and rivers. He indeed is the agent. 

Similarly in verse 13:

4.3.13.    ‘In the dream world, the luminous one attains higher and lower  states and creates many forms – now, as it were, enjoying  himself in the company of women, now laughing, now even  beholding frightful sights. 

Next Yajnavalkya describes how the Self, referred here by the term Purusha, which literally means ‘supreme being’ or ‘supreme person’ (think ‘higher-self’), floats between two states, the dream state and waking state, but remains unaffected by theses states, returning to the state of deep sleep when not in dream or waking. He receives cattle for his teachings here:

15.    Yajnavalkya said: “The entity (purusha), after enjoying himself  and raoming in the dream state and merely witnessing the  results of good and evil, remians in a state of profound sleep  and then hastens back in the reverse way to his former  condition, the dream state. He remains unaffected by whatever  he sees in that dream state, for this infinite being is unattached.”  Janaka said: “Just so, Yajnavalkya. I give you, Sir, a thousand  cows.  Please instruct me further about Liberation itself. 

16.    “Yajnavalkya said: “That entity (purusha), after enjoying  himself and roaming in the dream state and merely witnessing  the results of good and evil, hastens back in the reverse way to  his former condition, the waking state. He remains unaffected  by whatever he sees in that state, for this infinite being is  unattached.”  Janaka said: “Just so, Yajnavalkya. I give you, Sir, a thousand  cows.  Please instruct me further about Liberation itself.”  

17.    Yajnavalkya said: “That entity (purusha), after enjoying  himself and roaming in the waking state and merely witnessing  the results of good and evil, hastens back in the reverse way to  its former condition, the dream state or that of dreamless sleep. 

18.    “As a large fish swims alternately to both banks of a river – the  east and the west – so does the infinite being move to both  these states: dreaming and waking. 

19.    “As a hawk or a falcon roaming in the sky becomes tired, folds  its wings and makes for its nest, so does this infinite entity  (purusha) hasten for this state, where, falling asleep, he  cherishes no more desires and dreams no more dreams. 

So we can see in the above verses Yajnavalkya has described the three states and how the Self remains unaffected by the 2 states of waking or dreaming. Now Yajnavalkya proceeds to teach more about the Self, comparing it to the ecstacy of sexual orgasm in which one loses all knowledge of the body mind and world, one loses all sense of fear and misery, and one feels completely and totally fulfilled, not desiring anything more and with no trace of suffering:

21.    “That indeed is his form-free from desires, free from evils,  free from fear. As a man fully embraced by his beloved wife  knows nothing that is without, nothing that is within, so does  this infinite being (the self), when fully embraced by the  Supreme Self, know nothing that is without, nothing that is  within.  “That indeed is his form, in which all his desires are fulfilled, in  which all desires become the self and which is free from desires  and devoid of grief. 

Yajnavalkya then goes on to say that with realisation of the Self, everything is no longer what it appeared to be, and the Self is untouched by karma – good deeds and bad deeds – and also untouched by any suffering:

22.    “In this state a father is no father, a mother is no mother, the worlds are no worlds, the gods are no gods, the Vedas are no the Vedas. In this state a  thief is no thief, the killer of a noble brahmin is no killer, a chandala is no chandala, a paulkasa is no paulkasa, a monk is no monk, an ascetic is no ascetic.  “This form of his is untouched by good deeds and untouched by  evil deeds, for he is then beyond all the woes of his heart. 

He then states that even in deep sleep the Self exists as pure consciousness, not conscious of any object, for there are no objects in deep sleep, but conscious somehow nonetheless, for it’s nature is imperishable eternal consciousness:

23.    “And when it appears that in deep sleep it does not see, yet it is seeing though it does not see; for there is no cessation of the  vision of the seer, because the seer is imperishable. There is  then, however, no second thing separate from the seer that it  could see. 

The above verse is essentially repeated for all the senses and mind, but then culminates at verses 31 and 32. I have here included the full sanskrit and Shankara’s commentary for these important verses. The verses state that when objective phenomena appear, ie. in the dream or waking states, it appears as if we can see something separate from us or perceive something separate from us. This apparent perception is due to ignorance or illusion. However, when we return to deep sleep, that is the Self:

Verse 4.3.31:

यत्र वा अन्यदिव स्यात्, तत्रान्योऽन्यत्पश्येत्, अन्योऽन्यज्जिघ्रेत्, अन्योऽन्यद्रसयेत्, अन्योऽन्यद्वदेत्, अन्योऽन्यच्छृणुयात्, अन्योऽन्यन्मन्वीत, अन्योऽन्यत्स्पृशेत्, अन्योऽन्यद्विजानीयात् ॥ ३१ ॥

yatra vā anyadiva syāt, tatrānyo’nyatpaśyet, anyo’nyajjighret, anyo’nyadrasayet, anyo’nyadvadet, anyo’nyacchṛṇuyāt, anyo’nyanmanvīta, anyo’nyatspṛśet, anyo’nyadvijānīyāt || 31 “||

31. In the waking and dream states, when there is something else, as it were, then one can see something, one can smell some-thing, one can taste something, one can speak something, one can hear something, one can think something, one can touch something, or one can know something.

Shankara’s commentary on 4.3.31:

It has been said that in the state of profound sleep there is not, as in the waking and dream states, that second thing [ie. objects] differentiated from the self which it can know; hence it knows no particulars [ie. objects] in profound sleep. Here it is objected: If this is its nature, why does it give up that nature and have particular knowledge [of objects]? If, on the other hand, it is its nature to have this kind of knowledge, why does it not know particulars [ie. objects] in the state of profound sleep? The answer is this: When, in the waking or dream state, there is something else besides the self, as it were, presented by ignorance, then one, thinking of oneself as different from that something—although there is nothing different from the self, nor is there any self different from it—can see something. This has been shown by a referrence to one’s experience in the dream state in the passage, ‘As if he were being killed, or overpowered’(IV. iii. 20). Similarly one can smell, taste, speak, hear, think, touch and know something.

Verse 4.3.32:

सलिल एको द्रष्टाद्वैतो भवति, एष ब्रह्मलोकः सम्राडिति हैनमनुशशास याज्ञवल्क्यः, एषास्य परमा गतिः, एषास्य परमा संपत्, एषोऽस्य परमो लोकः, एषोऽस्य परम आनन्दः; एतस्यैवानन्दस्यान्यानि भूतानि मात्रामुपजीवन्ति ॥ ३२ ॥

salila eko draṣṭādvaito bhavati, eṣa brahmalokaḥ samrāḍiti hainamanuśaśāsa yājñavalkyaḥ, eṣāsya paramā gatiḥ, eṣāsya paramā saṃpat, eṣo’sya paramo lokaḥ, eṣo’sya parama ānandaḥ; etasyaivānandasyānyāni bhūtāni mātrāmupajīvanti || 32 ||

32. In the deep sleep state, it becomes (transparent) like water, one, the witness, and without a second. This is the world (state) of Brahman, O Emperor. Thus did Yājñavalkya instruct Janaka: This is its supreme attainment, this is its supreme glory, this is its highest world, this is its supreme bliss. On a particle of this very bliss other beings live.

Shankara’s commentary on 4.3.32:

When, however, that ignorance which presents things other than the self is at rest, in that state of profound sleep, there being nothing separated from the self by ignorance, what should one see, smell, or know, and through what? Therefore, being fully embraced by his own self-luminous Supreme Self, the Jīva becomes infinite, perfectly serene, with all his objects of desire attained, and the self the only object of his desire, transparent like water, one, because there is no second: It is ignorance which separates a second entity, and that is at rest in the state of profound sleep; hence ‘one.’ The witness, because the vision that is identical with the light of the self is never lost. And without a second, for there is no second entity different from the self to be seen. This is immortal and fearless. This is the world of Brahman, the world that is Brahman: In deep sleep the self, bereft of its limiting adjuncts, the body and organs, remains in its own supreme light of the Ātman [the Self], free from all relations, O Emperor. Thus did Yājñavalkya instruct Janaka. This is spoken by the Śruti.

How did he instruct him? This is its supreme attainment, the attainment of the individual self.

The other attainments, characterised by the taking of a body, from the state of Hiraṇyagarbha down to that of a clump of grass, are created by ignorance and therefore inferior to this, being within the sphere of ignorance. But this identification with all, in which one sees nothing else, hears nothing else, knows nothing olse, is the highest of all attainments such‘as identity with the gods, that are achieved through meditation and rites. This too is its supreme glory, the highest of all its splendours, being natural to it; other glories are artificial. Likewise this is its highest world; the other worlds, which are the result of its past work, are inferior to it; this, however, is not attainable by any action, being natural; hence ‘this is its highest world.’ Similarly this is its supreme bliss, in comparison with the bther joys that are due to the contact of the organs with their objects, since it is eternal; for another Śruti says, ‘That which is infinite is bliss’ (Ch. VII. xxiii. 1). ‘That in which one sees something. . . . knows something, is puny,’ mortal, secondary joy. But this is the opposite of thathence ‘this is its supreme bliss.’ On a particle of this very bliss, put forward by ignorance, and perceived only during the contact of the organs with their objects, other beings live. Who are they? Those that have been separated from that bliss by ignorance, and are considered different from Brahman. Being thus different, they subsist on a fraction of that bliss which is perceived through the contact of the organs with their objects.

Tom’s concluding remarks:

We can see that in the above two verses Shankara and Yajnavalkya are stating that:

-The Self cannot be attain by various karmas or works, for these are relating to objective phenomena only which occur only in the dream and waking states. ie. works or practices can only occur in the waking or dream states.

-However, the Self already is, it is already our True Actual Nature, naturally unattached and unaffected by it all, naturally beyond desire and suffering, its nature being happiness or bliss and oneness in which there is no sense of other.

– In deep sleep, when there are no adjuncts, ie. objective phenomena such as body or mind, then there is only the Self. Shankara states ‘this is spoken by shruti’, shruti referring to the revealed scriptures that are the vedas and upanishads, meaning that this teaching comes from the highest authority.

– All else, ie. all objective phenomena, are created and presented to us by ignorance, and so we are separated from the Bliss of Brahman by our seeing of objects ‘outside of us’.

The Upanishad tell us Thus did Yājñavalkya instruct Janaka

Note that a clear and direct method for realisation is not given in this section of the Upanishad, although it is hinted at. For more on this see here which is where the instruction for liberation is given in the Brihadaranyaka Upanishad by our friend Sage Yajnavalkya.

Note that this above section of the Brihadaranyaka Upanishad also tallies with and is indirectly explained further by Sri Ramana Maharshi’s method of wakeful-sleep, a wonderful and simple explanation of the path to liberation.

What we truly desire

Tom Das peace of deep sleep

What we desire…

We desire to be happy always without misery. What is this happiness? It’s not normal happiness, what you might think of, but the peace of deep sleep. To put it differently,  it’s the Peace of death whilst alive.

It’s when there is no mind. This is what we search for, we search for the mind to end. That’s what we really want.

When mind ends what you are is.

When you let go of everything…what is true, what is unchanging, what will never be destroyed, will be there fully.


When you let go of everything, that which is true, which cannot be destroyed, which is pure, that which always is…that God, that Divine, that One, that holiness, that will be there. Always…

So why worry?

If we can have faith in that, just let go of everything and That will be there. You don’t have to look for it, because it’s real. Everything else that is false will fall away. That which is real will be there.

And in your life you’ve got to do, what you’ve got to do. You have your responsibilities, you have to do those responsibilities. You just get on with it. They are not an obstacle. You look after your body, mind, you look after other body minds. Be as good person as you can be in this society. Knowing that this Divinity is always there.

Ramana Maharshi: a quick and simple method to self-realisation

In the deep sleep state we lay down our ego [ahankara],
our thoughts and our desires.

If we could only do all this while we are conscious,
we would realise the Self.
