BG 16.20

Attaining repeated birth amongst the species of demoniac life, O son of Kuntī, such persons can never approach Me. Gradually they sink down to the most abominable type of existence.

16.20. Having come to the demoniac womb, birth after birth, and not attaining Me at all, these deluded persons, therefore, pass to the lowest state, O son of Kunti !

16.20 So reborn, they spend life after life, enveloped in delusion. And they never reach Me, O Prince, but degenerate into still lower forms of life.

16.17-20 Atmasambhavitah etc. upto gatim. They pretend to perform sacrifices : The meaning is that their sacrifice is fruitless. Indeed all is ruined because of their anger. Or, namayjna [may mean] 'the sacrifices which are in name only'. Or, it [may denote] those sacrifices that are performed for one's name sake i.e., for one's reputation, because of which one gets the appellation as 'He is performer of [such and such] sacrifices' These sacrifices, performed out of hypocricy alone, do not , however fetch any fruit. Becasue these persons are rugged with anger etc., they hate people and by that they hate Me only [in fact]. For, I, the Vasudeva (the Universal Soul), dwell every-where. Entertaining hatred towards their own Soul, they perform action, that is hostile to themselves, and responsible for their own fall into the hells. These persons I hurl into nothing but the demoniac wombs.

16.20 'These deluded men,' viz., those entertaining perverse knowledge about Me, attain repeatedly births that tend them to be antagonistic to Me. Never 'attaining Me,' viz., never arriving at the knowledge that Vasudeva, the Lord and the ruler of all, truly exists, they go farther and farther down, from that birth, to the lowest level. Sri Krsna proceeds to explain the root-cause of the ruin to the self of demoniac nature:

16.20 Apannah, being born, having acired; (births) asurim, among the demoniacal; yonim, species; janmani janmani, in births after births; the mudhah, fools, non-discriminating ones; being born in every birth into species in which tamas prevails, and going downwards, aprapya eva, without ever reaching, approaching; mam, Me, who am God; O son of Kunti, yanti, they attain; gatim, conditions; tatah adhamam, lower even than that. Since there is not the least possibility of attaining Me, what is implied by saying, 'without ever reachin Me', is, 'by not attaining the virtuous path enjoined by Me.' This is being stated as a summary of all the demoniacal alities. The triplet-under which are comprehended all the different demoniacal alities though they are infinite in number, (and) by the avoidance of which (three) they (all the demaniacal alities) become rejected, and which is the root of all evils- is being stated:

16.20 Fallen into demoniac wombs in birth after birth, these deluded men, not attaining Me, further sink down to the lowest level, O Arjuna.

16.20 Being born among the demoniacal species in births after births, the foods, without ever reaching Me, O son of Kunti, attain conditions lower than that.
