Srimad-Bhagavatam: Canto 11 - Chapter 1 - Verse 26
Sanskrit:
तावत् स मोदते स्वर्गे यावत् पुण्यं समाप्यते ।क्षीणपुण्य: पतत्यर्वागनिच्छन् कालचालित: ॥ २६ ॥
ITRANS:
tāvat sa modate svargeyāvat puṇyaṁ samāpyatekṣīṇa-puṇyaḥ pataty arvāganicchan kāla-cālitaḥ
Translation:
Until his pious results are used up, the performer of sacrifice enjoys life in the heavenly planets. When the pious results are exhausted, however, he falls down from the pleasure gardens of heaven, being moved against his desire by the force of eternal time.
