From brooding comes attachment; from attachment, desire; from desire, anger. Krishna maps the inner chain so you can break it before it breaks you.
ध्यायतो विषयान्पुंसः सङ्गस्तेषूपजायते। सङ्गात् संजायते कामः कामात्क्रोधोऽभिजायते।।2.62।।
When a person dwells on the objects of sense, they create an attraction for them; this attraction develops into desire, and desire breeds anger.
क्रोधाद्भवति संमोहः संमोहात्स्मृतिविभ्रमः। स्मृतिभ्रंशाद् बुद्धिनाशो बुद्धिनाशात्प्रणश्यति।।2.63।।
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.
श्री भगवानुवाच काम एष क्रोध एष रजोगुणसमुद्भवः। महाशनो महापाप्मा विद्ध्येनमिह वैरिणम्।।3.37।।
Lord Shri Krishna: It is desire, it is aversion, born of passion. Desire consumes and corrupts all things. It is the greatest enemy of man.
त्रिविधं नरकस्येदं द्वारं नाशनमात्मनः।कामः क्रोधस्तथा लोभस्तस्मादेतत्त्रयं त्यजेत्।।16.21।।
The gates of hell are three: lust, wrath, and avarice; they destroy the Self, so avoid them.
शक्नोतीहैव यः सोढुं प्राक्शरीरविमोक्षणात्। कामक्रोधोद्भवं वेगं स युक्तः स सुखी नरः।।5.23।।
He who, before leaving his body, learns to overcome the promptings of desire and anger, is a saint and is happy.
दुःखेष्वनुद्विग्नमनाः सुखेषु विगतस्पृहः। वीतरागभयक्रोधः स्थितधीर्मुनिरुच्यते।।2.56।।
The sage whose mind is unruffled in suffering, whose desire is not aroused by enjoyment, who is without attachment, anger, or fear—take him to be one who stands at a lofty level.
श्री भगवानुवाच अभयं सत्त्वसंशुद्धिः ज्ञानयोगव्यवस्थितिः। दानं दमश्च यज्ञश्च स्वाध्यायस्तप आर्जवम्।।16.1।।
Lord Shri Krishna continued: Fearlessness, clean living, unceasing concentration on wisdom, readiness to give, self-control, a spirit of sacrifice, regular study of the scriptures, austerity, candor,
