SB 7.15.16
santustasya nirihasya
svatmaramasya yat sukham
kutas tat kama-lobhena
dhavato ’rthehaya disah
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
One who is content and satisfied and who links his activities with the Supreme Personality of Godhead residing in everyone’s heart enjoys transcendental happiness without endeavoring for his livelihood. Where is such happiness for a materialistic man who is impelled by lust and greed and who therefore wanders in all directions with a desire to accumulate wealth?
