Chapter XIII · Śloka 12
अध्यात्मज्ञाननित्यत्वं तत्त्वज्ञानार्थदर्शनम् ।
एतज्ज्ञानमिति प्रोक्तमज्ञानं यदतोऽन्यथा ॥
adhyātma-jñāna-nityatvaṃ tattva-jñānārtha-darśanam |
etaj jñānam iti proktam ajñānaṃ yad ato'nyathā ||
Constancy in Self-knowledge and perception of the goal of true wisdom — all this is declared to be knowledge; whatever is contrary to this is ignorance.
The twentieth and final quality of jñāna is unbroken abidance in Self-inquiry culminating in the vision of ultimate Truth. Everything that moves away from this — pride, attachment, confusion — is ajñāna, regardless of intellectual content.
