Verse
चिन्तामपरिमेयां च प्रलयान्तामुपाश्रिताः ।कामोपभोगपरमा एतावदिति निश्चिताः ॥
They imagine that desire and enjoyment are all the aim of life and (in their inordinate and insatiable pursuit of it) they are the prey of a devouring, a measurelessly unceasing care and thought and endeavour and anxiety till the moment of their death.
Gītā 16·11
