Premanand Maharaj Ji
How can an ordinary person do seva with little money or time?
Serve with body, mind and wealth
Seva is done with tan (body), man (mind) and dhan (wealth), and anyone can do it. Saving wasteful spending and putting it toward cows, saints or the sick brings Bhagwan's pleasure.
Stop wasting money here and there. Say ₹100 is saved and goes to a cow shelter, and green grass worth ₹1 is put out; that becomes seva.
