Srimad Bhagavatam Canto 11, Chapter 25, Text 14

SB 11.25.14

yada jayet tamah sattvam
 rajah sangam bhida calam
tada duhkhena yujyeta
 karmana yasasa sriya
 
Translation: 
 
When the mode of passion, which causes attachment, separatism and activity, conquers ignorance and goodness, a man begins to work hard to acquire prestige and fortune. Thus in the mode of passion he experiences anxiety and struggle.
