There are three gates to this hell that destroy the soul: desire, anger, and greed. Therefore one must abandon these three.

One of the Gita's most practically useful verses: three gates to hell (and simultaneously, three destroyers of the soul) — kāma (desire, lust), krodha (anger), and lobha (greed). They are called gates because they are entry points: passing through any one of them leads into the territory described in the preceding verses. They are also nāśanam ātmanaḥ — destroyers of the Self, forces that progressively erode one's connection to one's own deepest nature. The instruction is simple and total: tyajet — abandon these three. Not manage them, not moderate them, not indulge them in moderation — abandon them. This does not mean the suppression of desire, the denial of anger's information, or the elimination of all material motivation, but rather the freedom from being driven by them as masters.
