Bhagavad Gita 13.11

अध्यात्मज्ञाननित्यत्वं तत्त्वज्ञानार्थदर्शनम्।एतज्ज्ञानमिति प्रोक्तमज्ञानं यदतोन्यथा॥

adhyātmajñānanityatvaṃ tattvajñānārthadarśanam |etajjñānamiti proktamajñānaṃ yadatonyathā ||

Constancy in Self-knowledge, the perception of the end of true knowledge—this is declared to be knowledge, and what is opposed to it is ignorance.

Constant yearning for the knowledge of the Self, and pondering over the lessons of the great Truth—this is wisdom; all else is ignorance.

Our plain-language meaning of this verse is waiting for scholar review.
