Premanand Maharaj Ji
What did Pundalik gain by serving his parents?
Pundalik's service brought Bhagwan
Pundalik served his parents night and day, and Lord Vitthal came to give him darshan. Serving your parents pleases Bhagwan, even without other worship.
When Pundalik ji stayed night and day in the service of his parents, Lord Vitthal himself came to give darshan.
