Premanand Maharaj Ji
Whom should I serve, and how do seva and bhajan go together?
Serve guru, society, Bhagwan and body
Serve your guru, society, Bhagwan and even your own body, which is Bhagwan's temple. Seva and remembrance of Bhagwan are both necessary.
So serve your guru, serve society, serve Bhagwan, and serve your own body too. This body is Bhagwan's temple. Serve with that understanding, and do plenty of bhajan.
