Bhagavad Gita 18.31 Chapter 18, Verse 31

यया धर्ममधर्मं च कार्यं चाकार्यमेव च ।
अयथावत्प्रजानाति बुद्धिः सा पार्थ राजसी ॥१८.३१॥

yayā dharmamadharmaṃ ca kāryaṃ cākāryameva ca
ayathāvatprajānāti buddhiḥ sā pārtha rājasī

Meaning

The intellect by which one wrongly understands dharma and adharma, what should and should not be done — that intellect, O Partha, is rajasic.
