Constancy in the knowledge of the Self, and the vision of the end of the knowledge of Truth — this is said to be knowledge; the opposite is ignorance.

The summation of virtues: adhyātma-jñāna — knowledge of the Self — maintained nityatvam (constantly), not as sporadic insight but as continuous awareness.

Tattva-jñānārtha-darśanam — seeing the purpose of the knowledge of Truth. Knowledge has an end: liberation. Keeping this goal in view prevents distraction.

What is contrary (anyathā) to this is ajñāna — ignorance. Not mere absence of knowledge but wrong knowledge: identification with the field instead of the knower.
