Why do Krishna devotees call each other "Prabhu?"
by Laxmimoni dasi
Srila Prabhupada called all devotees, men and women, "Prabhu" (master). It means that a devotee sees all people, especially other devotees, as their master and that they are the servant. By thinking in this way one is respectful to all living entities and can develop a servant mentality rather than a master
mentality. To denote extra respect, sometimes the suffix "ji" is added, as in "Prabhuji." Serving comes in different forms...mostly to help others in their spiritual journey.
