Bhagavad Gita: Chapter 2, Verse 45

त्रैगुण्यविषया वेदा निस्त्रैगुण्यो भवार्जुन ।
निर्द्वन्द्वो नित्यसत्त्वस्थो निर्योगक्षेम आत्मवान् ॥ २-४५ ॥

trai-guṇya-viṣayā vedā nistrai-guṇyo bhavārjuna
nirdvandvo nitya-sattva-stho niryoga-kṣema ātmavān 2.45

The Vedas deal mainly with the subject of the three modes of material nature. O Arjuna, Rise above from these three modes to a pure state of spiritual existence. Be free from all dualities and from all anxieties for gain and safety, and be established in the self.
