Defined in the Gītā

Knowledge

What is knowledge?

Humility, pridelessness, nonviolence, tolerance, simplicity, approaching a bona fide spiritual master, cleanliness, steadiness and self-control; renunciation of the objects of sense gratification, absence of false ego, the perception of the evil of birth, death, old age and disease; nonattachment to children, wife, home and the rest, and evenmindedness amid pleasant and unpleasant events; constant and unalloyed devotion to Me, resorting to solitary places, detachment from the general mass of people; accepting the importance of self-realization, and philosophical search for the Absolute Truth—all these I thus declare to be knowledge, and what is contrary to these is ignorance.

Bhagavad-gītā 13.8–12

See the definition

Purport

Perfect knowledge of self and Superself and of their relationship is compared herein to fire. This fire not only burns up all reactions to impious activities, but also all reactions to pious activities, turning them to ashes. There are many stages of reaction: reaction in the making, reaction fructifying, reaction already achieved, and reaction a priori. But knowledge of the constitutional position of the living entity burns everything to ashes. When one is in complete knowledge, all reactions, both a priori and a posteriori, are consumed. In the Vedas it is stated: ubhe uhaivaiṣa ete taraty amṛtaḥ sādhv-asādhūnī: "One overcomes both the pious and impious interactions of work."

What this verse teaches

Results and glories of jñāna — no bewilderment, pure vision, and destruction of sins
