Jnana Yoga, the path of knowledge and wisdom, challenges us to know what we know. By questioning our selves regarding our beliefs and perceptions and studying the natural and man made orders of the world, we learn to examine and quiet our thoughts. By thoroughly knowing ourselves and our world, the follower of Jnana Yoga achieves liberation, perfect union.
“JNANA YOGA: THE YOGA OF WISDOM
Jnana (wisdom or knowledge) is considered the most difficult of the four main paths of Yoga, requiring great strength of will and intellect. In Jnana yoga, the mind is used to inquire into its own nature and to transcend the mind’s identification with its thoughts and ego. The fundamental goal of Jnana yoga is to become liberated from the illusionary world of maya (thoughts and perceptions) and to achieve union of the inner Self (Atman) with the oneness of all life (Brahman). This is achieved by steadfastly practicing the mental techniques of self-questioning, reflection and conscious illumination that are defined in the Four Pillars of Knowledge. ”
