Bhagavad Gita · Chapter 13: The Field and the Knower of the Field

Bhagavad Gita 13.11

adhyātmajñānanityatvaṃ tattvajñānārthadarśanam | etajjñānamiti proktamajñānaṃ yadato'nyathā ||

constancy in knowledge of the self, and insight into what knowledge of the truth is for: this is declared to be knowledge. Whatever is contrary to it is ignorance.

Modern context

The list ends with constancy in self-knowledge and seeing what knowledge of the truth is for. Then a bold statement: all this is knowledge, and whatever is contrary to it is ignorance. By this measure, a brilliant but arrogant, dishonest, restless person is ignorant, and a humble, patient, honest person with little education may be wise. Knowledge is redefined as a way of being.
