ऊर्ध्वं गच्छन्ति सत्त्वस्था मध्ये तिष्ठन्ति राजसाः ।
जघन्यगुणवृत्तिस्था अधो गच्छन्ति तामसाः ॥१४- १८॥

Transliteration

uurdhwaM gachChanti sattwasthaa madhye tiShThanti raajasaaH ।

jaghanyaguNawRRittisthaa adho gachChanti taamasaaH ॥१४- १८॥

Translation

Sattva-established go up. Rajas[-established] remain in the middle.
The tamas-established, in the nature of the lowest qualities, go down.

Translation

Those who are established in Sattva go to heaven; Raajasika persons are reborn in the mortal world; and the Taamasika persons, abiding in the lowest Guna, go to hell (or born as lower creatures).

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 mode of ignorance go down to the hellish worlds.
