Bhagavad Gita · Chapter 16: The Divine and the Demonic Natures
Bhagavad Gita 16.19
तानहं द्विषतः क्रूरान्संसारेषु नराधमान् ।
क्षिपाम्यजस्रमशुभानासुरीष्वेव योनिषु ॥
tānahaṃ dviṣataḥ krūrānsaṃsāreṣu narādhamān | kṣipāmyajasramaśubhānāsurīṣveva yoniṣu ||
Those cruel haters, the lowest of people, I cast again and again, in the cycle of rebirth, into demonic wombs.
Modern context
This is one of the harshest verses in the Gita: the cruel are cast again and again into demonic births. It can be read as a description of how character shapes destiny. Cruelty breeds cruelty; a person who chooses hatred moves into situations and relationships full of hatred, life after life. The verse is less a threat of punishment than a statement of consequence.
