By Swami Harshananda
Nirvikalpaka literally means ‘without distinctions’.
Vikalpa means distinctions, the consciousness of the many like ‘me’ and ‘Brahman’ and the world. In the savikalpaka samādhi the consciousness of one’s own personality as distinct from Brahman, however attenuated it may be. In the nirvikalpaka state all the awareness of multiplicity including that of oneself as distinct from Brahman, is completely dissolved.
