By Nirvikalpa Samadhi the truth of Brahman is clearly and definitely realised and all desires are destroyed
~ Vivekachudamani
360. The truth of the Paramatman is extremely subtle, and cannot be reached by the gross outgoing tendency of the mind. It is only accessible to noble souls with perfectly pure minds, by means of Samadhi brought on by an extraordinary fineness of the mental state.
361. As gold purified by thorough heating on the fire gives up its impurities and attains to its own lustre, so the mind, through meditation, gives up its impurities of Sattva, Rajas and Tamas, and attains to the reality of Brahman.
362. When the mind, thus purified by constant practice, is merged in Brahman, then Samadhi passes on from the Savikalpa to the Nirvikalpa stage, and leads directly to the realisation of the Bliss of Brahman, the One without a second.
363. By this Samadhi are destroyed all desires which are like knots, all work is at an end, and inside and out there takes place everywhere and always the spontaneous manifestation of one’s real nature.
364. Reflection should be considered a hundred times superior to hearing, and meditation a hundred thousand times superior even to reflection, but the Nirvikalpa Samadhi is infinite in its results.
365. By the Nirvikalpa Samadhi the truth of Brahman is clearly and definitely realised, but not otherwise, for then the mind, being unstable by nature, is apt to be mixed up with other perceptions.
366. Hence with the mind calm and the senses controlled always drown the mind in the Supreme Self that is within, and through the realisation of thy identity with that Reality destroy the darkness created by Nescience, which is without beginning.
