A pure devotee of Krsna, Theist, doesn`t care for any public opinion about himself. Because his only business, by Srila Narada`s example, is teaching others how to finally go home Back to Godhead. In the Narada Pancaratra it is stated: That all Vedic rituals, mantras and conclusions are compressed into just 8 words, Hare Krsna Hare Krsna Krsna Krsna Hare Hare. Having reached this level of knowledge, a pure devotee like Narada Muni if you happen to see him chanting Hare Krsna, is a person who`s impervious to all sorts of things that surrounds him.
