The following quotes, taken from the publication ‘The Shining of my Lord’ by Sri Muruganar, clearly and concisely explain the direct path to Self-Realisation.
In this context, the words ‘sadhana‘ and ‘tapas‘ both essentially mean spiritual practice.
‘Swarupa‘ means your own true nature, referring to the Self, the Ultimate Reality that you ARE.
The word ‘pure’ in the phrase ‘pure consciousness’ refers to consciousness devoid of any objects or arising phenomena, a reference again to the Self, your Swarupa.
I recommend you listen to this video in which the following quotes are read aloud for you, as this can often result in the same teachings being heard in a different and more powerful way:
502. The sadhana is to withdraw the mind from the sense objects of the world, which arise through the ignorance of taking the body to be ‘I’, and fix it in the feet of the Lord’s grace, pure consciousness. For those who are fully convinced of the efficacy of this sadhana, and who are able to practise it, there will be no need to abandon it to perform any other great tapas
503. Until everything shines wholly as swarupa, eschew all [perceived phenomena] as your enemies.
508. Those who abide as pure consciousness will experience the truth, the Self that exists as their own intimately close associate, but if the mind is allowed to move about among the senses through the pathways of the five senses, life will become shameful, losing its beauty.
509. If consciousness leaves the heart and manifests outwardly, it will experience perplexity through the false and deceitful sense objects. If it becomes extremely clear and remains firmly settled in consciousness-the-supreme, pure grace, and then merges with it, life will become blissful.
516. The ego deserves to be stigmatised whereas the Self alone deserves to be worshipped and saluted. Save and protect yourself completely from the treacherous maya, whose form is the ego, by the daily practice of abidance in the pure Self in order that the abidance may become firm and habitual.
492. For those who keenly desire as their principal priority a merger with the beauty of grace, the swarupa that abides in the heart as pure consciousness, it is not even slightly acceptable to have any connection with objects enjoyed by the senses, which are concepts of the fake entity, the deluding consciousness.
417. If we perform sadhana to the limit of our abilities, the Lord will accomplish for us that which is beyond our capabilities. If we fail to do even that which is within our capabilities, there is not the slightest fault in the grace of the Lord.
423. Devotion exists in many different forms, varying according to the quality of the devotee’s mind. However, only devotion to grace, the swarupa that shines as pure consciousness, enables one to reach directly the unsurpassed state of the supreme.
