Krodhad bhavati sammohah
sammohat smrti vibhramah
smriti bhramsad budhi-nasa
budhi nasat pranasyati
(Text 63, Contents of Gita Summarized)
Meaning: From anger, complete delusion arises, and from delusion bewilderment of memory. When memory is bewildered, intelligence is lost, and when intelligence is lost one falls down again into the material pool.
