READY TO OFFER RESPECT TO EVERYONE
Advanced devotee never disobey or disrespect another devotee. Disrespect to another devotee is a great offense. Vaisnava aparadha. Vaisnava aparadha is very serious offense.
Therefore we teach to address amongst the devotees, "Prabhu", "Prabhu", "Such and such Prabhu." This should not be simply spoken by the lips. It should be realized. Everyone should think other devotee as his prabhu, master. Not he should try to become master.
trnad api sunicena
taror api sahisnuna
Manadena. We should be always ready to offer respect to all, not only devotees, but everyone. Everyone. Because every living entity is originally a devotee of Krsna. But circumstantially, being covered by the coat of maya, he's playing like demon.
But his original nature is a devotee of Krsna. Jivera svarupa haya nitya krsnera dasa [Cc. Madhya 20.108-109]. Everyone is eternally servant of Krsna.
