Bhagwad Gita
Chapter 14, Verse 18
ऊर्ध्वं गच्छन्ति सत्त्वस्था मध्ये तिष्ठन्ति राजसाः।जघन्यगुणवृत्तिस्था अधो गच्छन्ति तामसाः।।14.18।।
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.
