The jivanmukta is one who has realized the invisible and unborn Soul, the Self, hidden by ignorance.+

A Gnani consciously becomes one with the Soul before his physical death, whereas the ignorant unconsciously becomes one with the Soul after his death.

Sage Sankara: ~ “Action (karma) cannot destroy ignorance, for it is not in conflict with or opposed to ignorance. Knowledge does verily destroy ignorance as light destroys deep darkness. -Atma Bodha

The Moksha is not a result of ritual action (karma marga) or of devotional or bhakti. The rituals and devotionally performed worship to an imaginary God within the illusory world with the illusory identity (you) will not yield any fruit.

Sage Sankara:- VC Let erudite scholars quote all the scripture, let Gods be invoked through sacrifices, let elaborate rituals be performed, let personal Gods be propitiated---yet, without the realization of one‘s identity With the ‘Self’, there shall be no liberation for the individual, not even in the lifetimes of a hundred Brahmas put together- (verses-6)

Advaitic Moksha is Gnanic Moksha. The Advaitic Moksha is synonymous with Brahman. Sruti says, "brahmavit brahmaiva bhavati" - He who knows Brahman becomes Brahman itself. It is not as if something that was not Brahman suddenly becomes Brahman. Rather, "realizing Brahman" means the removal of ignorance by realizing the Self is not an individual but the Soul, which pervades everywhere and in everything in the universe.

Thus, to "know Brahman" is to "be Brahman". The one who has realized the Soul, the ‘Self’, which is hidden by the dualistic illusion (Maya), is the jivanmukta, one who is liberated even while embodied. Such realization is possible by acquiring Self-knowledge or Brahma Gnana, or Atma Gnana.

Self-knowledge or Brahma Gnana or Atma Gnana itself is the Advaitic wisdom of Sage Sankara.

The jivanmukta is one who has realized the invisible and unborn Soul, the Self, hidden by ignorance.

Gnanic moksha is not a religiously propagated moksha. Religious propagated moksha is dualistic. The religion that propagates moksha is the result of ritual action (karma marga) or of devotional service (bhakti marga).

The religious propagated paths, not the liberation. Gnanic moksha is not a result of anything, for it always exists. All that is required is the removal of ignorance.

Advaitic realization comes only by getting rid of ignorance by perfect understanding and realization of ‘what is what’.  : ~ Santthosh Kumaar
