Bhagavad Gita
Chapter 2 · Verse 63
क्रोधाद्भवति सम्मोहः सम्मोहात्स्मृतिविभ्रमः। स्मृतिभ्रंशाद् बुद्धिनाशो बुद्धिनाशात्प्रणश्यति॥
krodhād bhavati sammohaḥ sammohāt smṛti-vibhramaḥ, smṛti-bhraṁśād buddhi-nāśo buddhi-nāśāt praṇaśyati
A chain reaction, traced step by step: unchecked anger clouds judgment long before it shows on the surface.
Anger left unchecked slowly clouds the mind. Notice it before it grows.
