Verse
अध्यात्मज्ञाननित्यत्वं तत्त्वज्ञानार्थदर्शनम् ।एतज्ज्ञानमिति प्रोक्तम् अज्ञानं यदतोऽन्यथा ॥
A meditative mind turned towards solitude and away from the vain noise of crowds and the assemblies of men, a philosophic perception of the true sense and large principles of existence, a tranquil continuity of inner spiritual knowledge and light, the Yoga of an unswerving devotion, love of God, the heart’s deep and constant adoration of the universal and eternal Presence; that is declared to be the knowledge; all against it is ignorance.
Gītā 13·12
