Nirvana – Wikipedia

Nirvana in Buddhism is “stilling mind, cessation of desires, and action” unto emptiness, states Jeaneane Fowler, while nirvana in post-Buddhist Hindu texts is also “stilling mind but not inaction” and “not emptiness”, rather it is the knowledge of true Self (Atman) and the acceptance of its universality and unity with metaphysical Brahman.
