Bhagavad Gita 6.8

ज्ञानविज्ञानतृप्तात्मा कूटस्थो विजितेन्द्रियः।युक्त इत्युच्यते योगी समलोष्टाश्मकाञ्चनः॥

jñānavijñānatṛptātmā kūṭastho vijitendriyaḥ |yukta ityucyate yogī samaloṣṭāśmakāñcanaḥ ||

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.

He who desires nothing but wisdom and spiritual insight, who has conquered his senses, and who looks upon a lump of earth, a stone, and fine gold with the same eye, is a real saint.

Our plain-language meaning of this verse is waiting for scholar review.
