This article is an excerpt from a much longer article which you can view here, that gives further quotes on this same topic from others including Sri Ramana Maharshi, Sri Shankara, Suresvara and Ribhu Gita. The original article also gives disclaimer which you should read (ie. these teachings are for earnest seekers only and can have detrimental effects for those not ready for them) and makes some suggestions as how to best appraoch these teachings.

The following verses are taken from the text Voga Vasistha Sara, which you can view and download here in its entirely. As with most Advaita texts, various teachings from different levels are given in this text. In Yoga Vasistha mainly Ajata Vada and Dristi Sristi Vada teachings are given, and below I will list some of the quotes pointing to Ajata Vada:

1.17 Even the slightest thought immerses a man in sorrow; when devoid of all thoughts he enjoys imperishable bliss.

1.23 Nothing whatever is born or dies anywhere at any time. It is Brahman alone appearing illusorily in the form of the world.

2.1 Just as the great ocean of milk became still when the Mandara Mountain (with which it was churned by the Devas and the Asuras) became still, even so the illusion of samsara comes to an end when the mind is stilled.

2.2 Samsara rises when the mind becomes active and ceases when it is still. Still the mind, therefore, by controlling the breath and the latent desires (vasanas).

2.3 This worthless (lit. burnt out) samsara is born of one’s imagination and vanishes in the absence of imagination. It is certain that it is absolutely unsubstantial.

2.5 This long-living ghost of a samsara which is the creation of the deluded mind of man [ie. ignorance] and the cause of his sufferings disappears when one ponders over it.

2.8 Whatever is seen does not truly exist. It is like the mythical city of Gandharvas (fata morgana) or a mirage.

2.11 This creation, which is a mere play of consciousness, rises up, like the delusion of a snake in a rope (when there is ignorance) and comes to an end when there is right knowledge.

2.19 The bliss of a man of discrimination, who has rejected samsara and discarded all mental concepts, constantly increases.

3.22 If, by perceiving that the objects of perception do not really exist, the mind is completely freed (from those objects) there ensues the supreme bliss of liberation.

3.23 Abandonment of all latent tendencies is said to be the best (i.e. real) liberation by the wise; that is also the faultless method (of attaining liberation).

3.24 Liberation is not on the other side of the sky, nor is it in the nether world, nor on the earth; the extinction of the mind resulting from the eradication of all desires is regarded as liberation.

3.25 O Rama, there is no intellect, no nescience, no mind and no individual soul (jiva). They are all imagined in Brahman.

3.26 To one who is established in what is infinite, pure consciousness, bliss and unqualified non-duality, where is the question of bondage or liberation, seeing that there is no second entity?

4.1 Consciousness which is undivided imagines to itself desirable objects and runs after them. It is then known as the mind.

4.9 The mind is the cause of (i.e. produces) the objects of perception. The three worlds depend upon it. When it is dissolved the world is also dissolved. It is to be cured (i.e. purified) with effort.

4.12 O Rama, he who, with in-turned mind, offers all the three worlds, like dried-grass, as an oblation in the fire of knowledge, becomes free from the illusions of the mind.

4.13 When one knows the real truth about acceptance and rejection and does not think of anything but abides in himself, abandoning everything, (his) mind does not come into existence.

4.14 The mind is terrible (ghoram) in the waking state, gentle (santam) in the dream state, dull (mudham) in deep sleep and dead when not in any of these three states [ie. when in the fourth state, Turiya, self-realisation].

4.16 The mind is samsara; the mind is also said to be bondage;

6.2 The mind, the intellect, the senses, etc. are all the play of Consciousness. They are unreal and seem to exist only due to lack of insight [ie. objects only appear due to lack or self-knowledge, which is also known as ignorance].

6.9 The world which has come into existence on account of my ignorance has dissolved likewise in me.

7.16 It is again strange that while the Supreme Brahman is forgotten by men, the idea ‘this is mine’ called avidya is firmly held by them (lit. strongly confronts them).

10.1 Supreme Bliss cannot be experienced through contact of the senses with their objects. The supreme state is that in which the mind is annihilated through one-pointed enquiry.

10.2 The bliss arising from the contact of the senses with their objects is inferior. Contact with the sense objects is bondage; freedom from it is liberation.

10.5 The belief in a knower and the known is called bondage. The knower is bound by the known; he is liberated when there is nothing to know.

10. 6 Abandoning the ideas of seer, seen and sight along with latent desires (vasanas) of the past, we meditate on that Self which is the primal light that is the basis of sight.

10.11 The rock-like state in which all thoughts are still and which is different from the waking and dream states, is one’s supreme state.

10.16 There is only the one waveless and profound ocean of pure nectar, sweet through and through (i.e. blissful) everywhere
