A jnani first engages in devotion to master the eligibility criteria to enter the path of jnana. The jnani then follows the eightfold path of jnana, jnana-marga to attain atmajnana. The practice involves chanting mahavakya's:
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 identifies himself to be a soul or jiva. He no longer identifies himself as the body, and therefore has no love or hate for anything material.
