SB 11.25.15
yada jayed rajah sattvam
tamo mudham layam jadam
yujyeta soka-mohabhyam
nidraya himsayasaya
Translation:
When the mode of ignorance conquers passion and goodness, it covers one’s consciousness and makes one foolish and dull. Falling into lamentation and illusion, a person in the mode of ignorance sleeps excessively, indulges in false hopes, and displays violence toward others.
