atmajnana | आत्मज्ञान
Atmajnana (Devanagari: आत्मज्ञान ISO15919: ātmajñāna ) means knowledge limited to that of the self. In this context self means jiva .
Jnani first does bhakti to master the eligibility criteria to enter the jnana-marg . Then jnani follows the eight fold path of jnana-marg to attain atmajnana . The practice involves chanting the mahavakya
तत् त्वम् असि
tat tvam asi
अहम् ब्रह्मास्मि
aham brahmāsmi
To start with there is a triad: jnanta , jneya , and jnana - the knower (mind), the known ( Brahm ) and the knowledge.
This means the jnani has now reached the state where he now identifies himself to be a jiva . He no longer identifies himself as body so has no love or hate for anything material.
