Srimad Bhagavatam Canto 08, Chapter 19, Text 25

SB 8.19.25

pumso ’yam samsrter hetur
 asantoso ’rtha-kamayoh
yadrcchayopapannena
 santoso muktaye smrtah
 
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
Material existence causes discontent in regard to fulfilling one’s lusty desires and achieving more and more money. This is the cause for the continuation of material life, which is full of repeated birth and death. But one who is satisfied by that which is obtained by destiny is fit for liberation from this material existence.
