The role of a sanyasi (monk) can be likened to a species of fish. The fish moves around in the depth of the lake; it does not stay at one spot. And while moving around, it eats up worms and the eggs of pests, thus cleansing the water. So too, the sanyasi should always be on the move, journeying into the far corners of the land. His duty is to cleanse the society of evil by his example and precept. He must transform it by his teachings into a society free from vice and wickedness.

- Vidya Vahini, Chapter XI.

You must serve with Heads in the Forest, Hands in the Society.  - Baba
