Translation

BG 16.19-20: These cruel and hateful persons, the vile and vicious of humankind, I constantly hurl into the wombs of those with similar demoniac natures in the cycle of rebirth in the material world. These ignorant souls take birth again and again in demoniac wombs. Failing to reach Me, O Arjun, they gradually sink to the most abominable type of existence.

Commentary

Shree Krishna once again describes the repercussions of the demoniac mentality. He says that in their next lives, he gives them birth in families with similar mentalities, where they get a suitable demoniac environment to exercise their free will and heartily vent their degraded nature. From this verse, we can also infer that it is not in the soul’s hands to choose the species, abode, and environment of its next birth. God makes this decision according to the nature and karma of the individual. Thus, the demoniac are sent into lower and degraded wombs, even to the level of snakes, lizards, and scorpions, which are receptacles for the evil-minded.
