Bhagavad Gita 2.62
ध्यायतो विषयान्पुंसः सङ्गस्तेषूपजायते । सङ्गात्सञ्जायते कामः कामात्क्रोधोऽभिजायते ॥
dhyāyato viṣayān puṃsaḥ saṅgas teṣūpajāyate | saṅgāt sañjāyate kāmaḥ kāmāt krodho 'bhijāyate ||
Translation
In one dwelling on the objects of the senses, attachment to them arises. From attachment is born desire. From desire is born anger.
Reflection
Where did the anger you carried this week start as a thought you dwelt on?
Read this verse in its chapter: Chapter Two
The cascade. Dhyāyataḥ. Saṅgaḥ. Kāmaḥ. Krodhaḥ. Dwelling. Attachment. Desire. Anger. Four links in a chain, each producing the next. Krishna walks the reader through the mechanism by which one private mental act ends up in a public rupture. The dwelling is the start: not the seeing of the object, but the dwelling on it after it has passed out of sight. From the dwelling, the line lengthens. Notice that anger appears in the chain not as a primary emotion but as a derivative one. Three turns back, it was simply a thought rehearsed too long.
