Bhagavad Gita · 18.31

यया धर्ममधर्मं च कार्यं चाकार्यमेव च।अयथावत्प्रजानाति बुद्धिः सा पार्थ राजसी॥

yayā dharmam adharmaṁ cha kāryaṁ chākāryam eva cha ayathāvat prajānāti buddhiḥ sā pārtha rājasī

O Partha, that intellect which incorrectly understands dharma and adharma, what ought to be done and what ought not to be done — that intellect is rajasic.

— Bhagavad Gita 18.31
