Bhagavad Gita 3.37 Chapter 3, Verse 37

श्री भगवानुवाच

काम एष क्रोध एष रजोगुणसमुद्भवः ।
महाशनो महापाप्मा विद्ध्येनमिह वैरिणम् ॥३.३७॥

śrī bhagavānuvāca
kāma eṣa krodha eṣa rajoguṇasamudbhavaḥ
mahāśano mahāpāpmā viddhyenamiha vairiṇam

Meaning

The Lord said: It is desire, which turns into anger, born of the quality of rajas. It is all-devouring and very sinful. Know it to be the enemy here.
