Bhagavad Gita · 2.62

ध्यायतो विषयान्पुंसः सङ्गस्तेषूपजायते।सङ्गात्सञ्जायते कामः कामात्क्रोधोऽभिजायते॥

dhyāyato viṣhayān puṁsaḥ saṅgas teṣhūpajāyate saṅgāt sañjāyate kāmaḥ kāmāt krodho 'bhijāyate

When a person dwells on sense objects, attachment to them arises. From attachment springs desire, and from desire arises anger.
