Jnana Yoga: The Yoga of Knowledge
Also referred to as the path of wisdom, Jnana yoga is the practice of knowing oneself by exploring your true Self and its origins. Jnana yoga's primary objective is liberation from maya (illusionary world) and union between Atman (inner soul) and Brahman (ultimate reality), achieved through mental techniques such as self-questioning, reflection and conscious illumination.
Jnana yoga's non-dualist philosophy draws its foundation from Advaita Vedanta tradition found within Hindu scripture, particularly Vedas. Thus, its philosophy revolves around understanding that our individual self (Atman) and all aspects of nature (cosmos) are inseparable.
Viveka, Vairagya, Sama and Dama are the four key pillars of Jnana Yoga practice: Viveka (discrimination or discernment), Vairagya, Sama and Dama (abstinence from material objects and desires, dispassionate attitude toward society's obligations), and Dama (the absence of anger). By following these four practices consistently in life a seeker develops a deep understanding of truth which eventually leads to moksha (liberation from material bodies). The Bhagavad Gita provides more than enough details regarding this path!
