Anger

ध्यायतो विषयान्पुंसः सङ्गस्तेषूपजायते। सङ्गात् संजायते कामः कामात्क्रोधोऽभिजायते॥

When a person dwells on the objects of sense, they create an attraction for them; this attraction develops into desire, and desire breeds anger.

Simple meaning

Krishna explains how trouble starts: when you keep thinking about something you want, attachment grows; attachment becomes desire; and when desire is blocked, it turns into anger.

In real life

क्रोधाद्भवति संमोहः संमोहात्स्मृतिविभ्रमः। स्मृतिभ्रंशाद् बुद्धिनाशो बुद्धिनाशात्प्रणश्यति॥

Anger induces delusion; delusion leads to loss of memory; loss of memory results in the shattering of reason; and the destruction of reason leads to destruction.

Simple meaning

This continues the chain: anger clouds judgement, clouded judgement makes you forget what you know is right, and when good sense is lost, a person ruins things for themselves.

In real life

त्रिविधं नरकस्येदं द्वारं नाशनमात्मनः। कामः क्रोधस्तथा लोभस्तस्मादेतत्त्रयं त्यजेत्॥

The gates of hell are three: lust, wrath, and avarice; they destroy the Self, so avoid them.

Simple meaning

Krishna names three gates that lead a person to ruin: uncontrolled desire, anger and greed. They destroy your inner self, so guard against them.
