Prabhu is a person who feels he is nearer to God and feels that all the qualities of God are with him.

Balarama, the elder brother of Krishna is considered to be the personification of Ananta, the coiled serpent and couch of Sriman Narayana. Balarama was always associated with Krishna. How much ever greatness Lord Krishna had, he also had the same greatness. Prabhu is the person who immediately reflects the glory of the other person.
