Bhagavad Gita Chapter 14.18
ūrdhvaḿ gacchanti sattva-sthā
madhye tiṣṭhanti rājasāḥ
jaghanya-guṇa-vṛtti-sthā
adho gacchanti tāmasāḥ
Translation
Those situated in the mode of goodness gradually go upward to the higher planets; those in the mode of passion live on the earthly planets; and those in the abominable mode of ignorance go down to the hellish worlds.
