SB 5.26.30

A lowborn and abominable person who in this life becomes falsely proud, thinking “I am great,” and who thus fails to show proper respect to one more elevated than he by birth, austerity, education, behavior, caste or spiritual order, is like a dead man even in this lifetime, and after death he is thrown headfirst into the hell known as Ksärakardama. There he must great suffer great tribulation at the hands of the agents of Yamaräja.

PURPORT

One should not become falsely proud. One must be respectful toward a person more elevated than he by birth, education, behavior, caste or spiritual order. If one does not show respect to such highly elevated persons but indulges in false pride, he receives punishment in Ksärakardama.
