As stated in Bhagavad-gītā (BG 14.18):
- ūrdhvaṁ gacchanti sattva-sthā</dd>
- madhye tiṣṭhanti rājasāḥ
- adho gacchanti tāmasāḥ
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.
