One day, someone fell from the roof of the Gurdwara and was badly injured. Bhagat Puran Singh immediately rushed him to the local 'Mu Hospital'. Experiencing inner joy after helping the patient, he took a man with badly bleeding leg, full of vermin, to a hospital where he expressed his thanks to Ramjidas telling him, "Son! Now I can die a peaceful death." With this incident, the service of humanity became the mission of his life. Now he would wander here and there finding the injured, physically handicapped persons, taking them to the hospital. He also took care of them as his pocket and capability allowed. Once, he even washed the clothes of an old, poor beggar who was suffering from diarrhoea.
