The path of the Vedāntic discipline is the path of negation, "Neti", in which, by stern determination, all that is unreal is both negated and renounced. It is the path of jnāna, knowledge, the direct method of realizing the Absolute.
After the negation of everything relative, including the discriminating ego itself, the aspirant merges in the One without a Second, in the bliss of nirvikalpa Samādhi, where subject and object are alike dissolved. The soul goes beyond the realm of thought.
The domain of duality is transcended. Māyā is left behind with all its changes and modifications. The Real Man towers above the delusions of creation, preservation, and destruction. An avalanche of indescribable Bliss sweeps away all relative ideas of pain and pleasure, good and evil.
There shines in the heart the glory of the Eternal Brahman, Existence-Knowledge-Bliss Absolute. Knower, knowledge, and known are dissolved in the Ocean of one eternal Consciousness; love, lover, and beloved merge in the unbounded Sea of supreme Felicity; birth, growth, and death vanish in infinite Existence.
All doubts and misgivings are quelled for ever; the oscillations of the mind are stopped; the momentum of past actions is exhausted. Breaking down the ridge-pole of the tabernacle in which the soul has made its abode for untold ages, stilling the body, calming the mind, drowning the ego, the sweet joy of Brahman wells up in that superconscious state.
Space disappears into nothingness, time is swallowed in eternity, and causation becomes a dream of the past. Only Existence is. Ah! Who can describe what the soul then feels in its communion with the Self?
