Bhagavad Gita 6.8

ज्ञानविज्ञानतृप्तात्मा कूटस्थो विजितेन्द्रियः। युक्त इत्युच्यते योगी समलोष्टाश्मकाञ्चनः

jñāna-vijñāna-tṛiptātmā kūṭa-stho vijitendriyaḥ yukta ityuchyate yogī sama-loṣhṭāśhma-kāñchanaḥ

The Yogi who is satisfied with the knowledge and wisdom of the Self, who has conquered the senses, and to whom a clod of earth, a piece of stone, and gold are all the same, is said to have attained Nirvikalpa Samadhi.

जिसका अन्तःकरण ज्ञान-विज्ञानसे तृप्त है, जो कूटकी तरह निर्विकार है, जितेन्द्रिय है और मिट्टीके ढेले, पत्थर तथा स्वर्णमें समबुद्धिवाला है -- ऐसा योगी युक्त (योगारूढ़) कहा जाता है।
