Jnana, or Gyana, in Hinduism is the real knowledge – the intuitive
knowledge of the Supreme Truth. It is the knowledge of Brahman – the absolute.
This knowledge gives freedom from all sufferings. When jnana dawns in a person,
he realizes he is the eternal, pure and enlightened. He
realizes that he is not the mind, body and ego.
This knowledge is found the in Upanishads, Bhagavad Gita,
Yoga Vasishta, in the Puranas, Mahabharata, Ramayana and other holy texts.
All these texts categorically state that individual soul is
not separate from the universal soul (Brahman).
Brahman is the all – pervading ultimate reality, and thus
ever free from birth, growth, decay, death, pain, suffering, sickness etc., to
which the body remains subjected to.
Thus, individual soul is Sat Chit Ananda – truth, awareness
and bliss.
Even Jnana, if not used wisely will end up piling up ignorance.
Try to define Brahman, arrogance, being proud of once scholarly nature etc., are
part of this ignorance.
Brahman is indefinable it can only be realized.
