क्रोधाद्भवति संमोहः संमोहात्स्मृतिविभ्रमः। स्मृतिभ्रंशाद् बुद्धिनाशो बुद्धिनाशात्प्रणश्यति॥
krodhādbhavati saṃmohaḥ saṃmohātsmṛtivibhramaḥ smṛtibhraṃśād buddhināśo buddhināśātpraṇaśyati
Meaning
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.
Understanding this verse
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
In a heated argument, a man says something cruel to his father that he doesn't mean, and damages the relationship for months.
A trader angry about one loss makes impulsive revenge trades and loses far more than the original amount.
Try this today: Make a personal rule: no important message, decision or reply while angry. Wait at least 20 minutes.
