Bhagavad Gita · Chapter 2: The Path of Understanding
Bhagavad Gita 2.63
क्रोधाद्भवति संमोहः संमोहात्स्मृतिविभ्रमः ।
स्मृतिभ्रंशाद् बुद्धिनाशो बुद्धिनाशात्प्रणश्यति ॥
krodhādbhavati saṃmohaḥ saṃmohātsmṛtivibhramaḥ | smṛtibhraṃśād buddhināśo buddhināśātpraṇaśyati ||
From anger comes delusion; from delusion, confusion of memory; from confused memory, the ruin of understanding; and when understanding is ruined, a person is lost.
Modern context
The chain is completed. Anger clouds judgement. In that cloud we forget what we know: our values, what we have learned, who the other person is to us. With memory gone, the power to discern fails, and then a person does what ruins them. Anyone who has said something unforgivable in a rage has lived this verse.
