Premanand Maharaj Ji
What are the kinds of seva, and which is best?
Three kinds of seva
Seva is of three kinds: mental, physical and financial, and mental seva is the best. If you cannot serve with body or mind, put your earnings into serving cows, saints and Bhagwan.
The best seva is mental, the second is physical, and the third is financial. If you cannot serve with the body and the mind cannot settle.
