Jñāna yoga is the way of knowledge, one of the three paths taught in the Bhagavad Gītā alongside action and devotion. It proceeds by study, reflection and contemplation, discriminating the self from all that is not the self until its identity with Brahman is known directly. Advaita holds that knowledge alone liberates.
