Srimad-Bhagavatam: Canto 8 - Chapter 1 - Verse 25
Sanskrit:
पुंसोऽयं संसृतेर्हेतुरसन्तोषोऽर्थकामयो: ।यदृच्छयोपपन्नेन सन्तोषो मुक्तये स्मृत: ॥ २५ ॥
ITRANS:
puṁso ’yaṁ saṁsṛter heturasantoṣo ’rtha-kāmayoḥyadṛcchayopapannenasantoṣo muktaye smṛtaḥ
Translation:
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.
