Timing

Kumbha Mela is a massive pilgrimage in which Hindus gather at the Ganges river. It is celebrated at different locations depending on the position of the planet of Bahaspati (Jupiter) and the sun. When Jupiter and the sun are in the zodiac sign Leo (Simha Rashi) it is held in Trimbakeshwar, Nashik; when the sun is in Aries (Mesha Rashi) it is celebrated at Haradwar; when Jupiter is in Taurus (Vrishabha Rashi ) and the sun is in Capricorn (Makar Rashi) Kumbha Mela is celebrated at Prayag; and Jupiter and the sun are in Scorpio (Vrishchik Rashi) the Mela is celebrated at Ujjain. Each site's celebration dates are calculated in advance according to a special combination of zodiacal positions of Sun, Moon, and Jupiter.

The Ritual

The major event of the festival is ritual bathing at the banks of the river in whichever town it is being held. Nasik has registered maximum visitors amounted nearly to 75 million. 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 standardized. Kumbh Mela 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 ashes and powder dabbed on their skin per the requirements of ancient traditions. Some, called naga sanyasis, may not wear any clothes even in severe winter.

After visiting the Kumbh Mela of 1895, Mark Twain wrote: "It is wonderful, the power of a faith like that, that can make multitudes upon multitudes of the old and weak and the young and frail enter without hesitation or complaint upon such incredible journeys and endure the resultant miseries without repining. It is done in love, or it is done in fear; I do not know which it is. No matter what the impulse is, the act born of it is beyond imagination, marvelous to our kind of people, the cold whites."
