Bhagavad Gita 18.31 — Rajasic intellect
यया धर्ममधर्मं च कार्यं चाकार्यमेव च। अयथावत्प्रजानाति बुद्धिः सा पार्थ राजसी ॥
yayā dharmamadharmaṃ ca kāryaṃ cākāryameva ca | ayathāvatprajānāti buddhiḥ sā pārtha rājasī ||
Meaning
The intellect that cannot clearly tell right from wrong, or what should be done from what should not, is rajasic.
