From the seven hundred
काम एष क्रोध एष रजोगुणसमुद्भवःमहाशनो महापाप्मा विद्ध्येनमिह वैरिणम्
kāma eṣa krodha eṣa rajoguṇa-samudbhavaḥ mahāśano mahā-pāpmā viddhy enam iha vairiṇam

“It is desire, it is anger, born of the restless force in us, all-devouring and all-corrupting. Know this as the enemy here.”

Bhagavad Gita 3.37
In plain terms

Arjuna asks what drags a person into doing wrong even when they want to do right. The answer names no villain across the field: it is the wanting that is never satisfied, and the heat that rises when it is denied.

Naming it is half the work. Once desire and anger are seen as one force wearing two faces, you can watch it move in yourself with a little distance, and distance is the beginning of a choice.
