Kṛṣṇa continues the downward spiral: from anger comes complete delusion. When you are angry, you lose the ability to distinguish between right and wrong. You become ‘blind’ with rage. This delusion leads to the bewilderment of memory—you forget your values, your teachers, and the consequences of your actions. When memory is lost, the ‘buddhi’, or intelligence, is destroyed. You lose the capacity for rational thought. And when intelligence is gone, a person ‘praṇaśyati’—they perish or fall down into the material pool. They are ruined by their own internal chemistry. This is a precise psychological map of how even great people fall. It all starts with a single unchecked thought that leads to anger and eventually to the loss of sanity. Kṛṣṇa is showing Arjuna that his current emotional agitation is the beginning of a very dangerous path.
