पुंसोऽयं संसृतेर्हेतुरसन्तोषोऽर्थकामयोः ।
यदृच्छयोपपन्नेन सन्तोषो मुक्तये स्मृतः ॥
puṁso’yaṁ saṁsṛter hetur asantoṣo’rtha-kāmayoḥ |
yadṛcchayopapannena santoṣo muktaye smṛtaḥ ||
(Śrīmad Bhāgavatam: 8.19.25)
“[Vāmanadeva to Bali Mahārāja:] This dissatisfaction with objects and enjoyment [of them] is the cause of a living being’s saṁsāra, and satisfaction with that which is attained of its own accord is known to lead to mukti.”
