Bhagavad Gita · 14.5

सत्त्वं रजस्तम इति गुणाः प्रकृतिसम्भवाः।निबध्नन्ति महाबाहो देहे देहिनमव्ययम्॥

sattvaṁ rajas tama iti guṇāḥ prakṛti-sambhavāḥ nibadhnanti mahā-bāho dehe dehinam avyayam

Sattva, rajas, and tamas — these three gunas born of material nature bind the imperishable soul to the body, O mighty-armed one.

— Bhagavad Gita 14.5
