Bhagavad Gita 18.31

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

yayā dharmamadharmaṃ ca kāryaṃ cākāryameva ca |ayathāvatprajānāti buddhiḥ sā pārtha rājasī ||

That by which one wrongly understands dharma and adharma, and also what ought to be done and what ought not to be done—that intellect, O Arjuna, is rajasic (passionate).

The intellect that does not understand what is right and wrong, and what should be done and not done, is under the sway of Passion.

Our plain-language meaning of this verse is waiting for scholar review.
