Bhagavatapurana 2.4.21

2.4.21

yadaṅghryabhidhyānasamādhidhautayā dhiyānupaśyanti hi tattvam ātmanaḥ /
vadanti caitat kavayo yathārucaṃ sa me mukundo bhagavān prasīdatām //

21. May that Bhagavan Mukunda be gracious unto me, by the yoga of contemplating whose feet the wise purify their power of understanding and thereby see (realise) the true nature of Atman, and discourse upon it, according as their tastes direct them (or as their light enables them to do).
