Bhagavad Gita · Chapter 14: The Three Qualities of Nature

Bhagavad Gita 14.15

rajasi pralayaṃ gatvā karmasaṅgiṣu jāyate | tathā pralīnastamasi mūḍhayoniṣu jāyate ||

One who dies when passion is dominant is born among those who are attached to action. One who dies when inertia is dominant is born among the deluded.

Modern context

One who dies in rajas is reborn among the restless and busy; one who dies in tamas, among the confused. Whatever one thinks of rebirth, the principle holds within a single life too. A person who lives in constant striving finds themselves surrounded by striving people. A person who lives in dullness drifts toward dull company. We tend to arrive where our habits are already pointing.
