The Yoga of Knowledge

This verse completes the cascade from 2.62. From anger (krodhāt) arises delusion (sammohaḥ)—you can't see clearly anymore. From delusion comes memory confusion (smṛti-vibhramaḥ)—you forget your values, who you are. From memory loss comes destroyed discrimination (buddhi-nāśaḥ)—you can't tell right from wrong. From destroyed discrimination, you perish (praṇaśyati)—complete ruin. The full chain: dwelling→attachment→desire→anger→delusion→memory loss→destroyed judgment→ruin. Each stage feeds the next automatically.
