नायमात्मा प्रवचनेन लभ्यो न मेधया न बहुना श्रुतेन । यमेवैष वृणुते तेन लभ्यः तस्यैष आत्मा विवृणुते तनू स्वाम् ॥

This Atman cannot be attained by the study of the Vedas, or by intelligence, or by much hearing of sacred books. It is attained by him alone whom It chooses. To such a one Atman reveals Its own form.
