Srimad-Bhagavatam: Canto 6 - Chapter 1 - Verse 45

Sanskrit:

येन यावान्यथाधर्मो धर्मो वेह समीहित: ।स एव तत्फलं भुङ्क्ते तथा तावदमुत्र वै ॥ ४५ ॥

ITRANS:

yena yāvān yathādharmodharmo veha samīhitaḥsa eva tat-phalaṁ bhuṅktetathā tāvad amutra vai

Translation:

In proportion to the extent of one’s religious or irreligious actions in this life, one must enjoy or suffer the corresponding reactions of his karma in the next.

Purport:

As stated in Bhagavad-gītā (14.18): Those who act in the mode of goodness are promoted to higher planetary systems to become demigods, those who act in an ordinary way and do not commit excessively sinful acts remain within this middle planetary system, and those who perform abominable sinful actions must go down to hellish life.
