Bhagwad Gita (Chapter 2, Verse 62,63) - Manushya ka patan kaise hota hai?

dhyāyato viṣhayān puṁsaḥ saṅgas teṣhūpajāyate
saṅgāt sañjāyate kāmaḥ kāmāt krodho ’bhijāyate
While contemplating on the objects of the senses, one develops attachment to them. Attachment leads to desire, and from desire arises anger.
krodhād bhavati sammohaḥ sammohāt smṛiti-vibhramaḥ
smṛiti-bhranśhād buddhi-nāśho buddhi-nāśhāt praṇaśhyati
Anger leads to clouding of judgment, which results in bewilderment of memory. When memory is bewildered, the intellect gets destroyed; and when the intellect is destroyed, one is ruined.
