Bhagavad Gita · 3.28

तत्त्ववित्तु महाबाहो गुणकर्मविभागयोः।गुणा गुणेषु वर्तन्त इति मत्वा न सज्जते॥

tattva-vit tu mahā-bāho guṇa-karma-vibhāgayoḥ guṇā guṇeṣhu vartanta iti matvā na sajjate

But one who knows the truth about the two divisions of the modes of nature and their actions, O mighty-armed one, knowing that the modes interact with the modes, does not become attached.

— Bhagavad Gita 3.28
