Śrīmad-Bhāgavatam
[Canto 5, Ch. 26]
that:  eva —only:  atibībhatsitam —extremely disgusting;  aśnanti —they eat.
TRANSLATION
The shameless husbands of lowborn śūdra women live exactly like animals, and therefore they have no good behavior, cleanliness or regulated life. After death, such persons are thrown into the hell called Pūyoda, where they are put into an ocean filled with pus, stool, urine, mucus, saliva and similar things. Śūdras who could not improve themselves fall into that ocean and are forced to eat those disgusting things.

Thus even a born  śūdra  is expected to become a  brāhmaṇa ; that is the meaning of human life. Everyone should improve himself. Kṛṣṇa says in  Bhagavad-gītā  (4.13),  cātur-varṇyam mayā sṛṣṭam guṇa-karma-vibhāgaśaḥ : “According to the three modes of material nature and the work ascribed to them, four divisions of human society were created by Me.” Even if one is by qualification a  śūdra , he must try to improve his position and become a  brāhmaṇa . No one should try to check a person, no matter what his present position is, from coming to the platform of a
