This is one of the most famous and practical verses in the Gita. Krishna distills the entire complex pathology of the demoniac nature into three root causes. He declares that there are three specific gates leading to hell and the total destruction of the soul (tri-vidhaṁ narakasyedaṁ dvāraṁ nāśanam ātmanaḥ). What are they? Lust (kāmaḥ), Anger (krodhas), and Greed (lobhas). Therefore, any sane person must immediately give up these three (tasmād etat trayaṁ tyajet).
