Watch how it arrives. You dwell on something; attachment forms; the attachment is threatened; craving flares — and craving's other face is anger. Krishna traces that chain in three verses and does not moralise about it. He calls it mechanical, the way weather is mechanical. Anger is not a character flaw in the Gītā. It is a force — born of restlessness, all-devouring, the enemy — and it does specific damage: it clouds judgement, collapses memory, and pulls the self apart. But Krishna does not ask you to suppress it. He names it one of the three gates to ruin and then says: step free. The instruction is not to never feel anger but to stop walking through the gate. These verses show you where the gate is, and what lies on the other side.
