Premanand Maharaj Ji
सच्ची सेवा की पहचान क्या है और सेवा किसकी करनी चाहिए?
Seva means bearing hardship without anger
Bearing the adversity the master gives without anger is what makes it seva; otherwise it is selfishness. Serve people, animals and parents too, since Bhagwan is in them.
When a servant can bear the hardship caused by the master, that is called seva. Otherwise it is selfishness, and then he is no longer a servant.
