Bhagavad Gita 2.45
The Vedic Scriptures tell of the three constituents of life—the Qualities. Rise above all of them, O Arjuna, above all the pairs of opposing sensations; be steadfast in truth, free from worldly anxieties, and centered in the Self.
त्रैगुण्यविषया वेदा निस्त्रैगुण्यो भवार्जुन।
निर्द्वन्द्वो नित्यसत्त्वस्थो निर्योगक्षेम आत्मवान्॥traiguṇyaviṣayā vedā nistraiguṇyo bhavārjuna|
