Bhagavad Gita · 2.45

त्रैगुण्यविषया वेदा निस्त्रैगुण्यो भवार्जुन।निर्द्वन्द्वो नित्यसत्त्वस्थो निर्योगक्षेम आत्मवान्॥

trai-guṇya-viṣhayā vedā nistrai-guṇyo bhavārjuna nirdvandvo nitya-sattva-stho niryoga-kṣhema ātmavān

The Vedas deal with the three gunas. O Arjuna, be free from the three gunas, free from duality, ever established in purity, without concern for acquisition and preservation, and established in the Self.
