The major event of the Simhastha festival is ritual bathing at the banks of the Kshipra river Other activities include religious discussions, devotional singing, mass feeding of holy men and women and the poor, and religious assemblies where doctrines are debated and standardised. Simhastha or Kumbha is the most sacred of all the pilgrimages. Thousands of holy men and women attend, and the auspiciousness of the festival is in part attributable to this. The sadhus are seen clad in saffron sheets with Vibhuti ashes dabbed on their skin as per the requirements of ancient traditions. Some, called naga sanyasis, may not wear any clothes even in severe winter.The right to be naga, or naked, is considered a sign of separation from the material world.
