Explanation:

Sarhul is spring festival celebrated during spring season when the Saal trees get new flowers on their branches. It is a worship of the village deity who is considered to be the protector of the tribes. People sing and dance a lot when the new flowers appear. The deities are worshiped with saal flowers. The village priest or Pahan fasts for a couple of days. In the early morning he takes a bath and puts on new a dhoti made of virgin cotton (kachha dhaga). The previous evening, the Pahan takes three new earthen pots and fills them with fresh water; the next morning he observes these earthen pots and water level inside. If the water level decreases he predicts that there would be famine or less rain, and if the water level is normal, that is the signal of a good rain.
