Jnana (sometimes written gyana) is considered the most difficult path, because it requires a radical shift in perception. The goal is to seek the knowledge hidden in all of us through questioning, meditation, and contemplation. Before practicing jnana yoga, the student needs to have integrated the lessons of the other yogic paths, for without selflessness, love of God, and the strength of body and mind, the search for self-realization is nothing more than an exercise in philosophy. The jnana student uses the mind to explore his or her own nature and to find knowledge through God.
