Gita for Anger, Desire, and Self-Control

Why do I snap or crave things I know are bad for me?

It is not weak to admit that anger and desire hijack you—Krishna names them as real enemies, not small moods. Why does want show up dressed as logic? Where does it live in the body? And how does the Gita say the deeper Self can cut it at the root? These verses are for the moment you already regret what you are about to do.
