Haridwar, India (CNN) -- The Kumbh Mela is a mass Hindu pilgrimage that is often referred to as the largest religious gathering on the planet. It is celebrated four times every 12 years, with the observance rotating between four different cities in India.
Thousands of spiritual Sadhus and Babas -- the holy men of India -- are the focal point, along with the millions of pilgrims who travel across India to attend the auspicious gathering and bathe in sacred rivers.
According to astrologers, the 'Kumbh' is to take place when the planet Jupiter enters Aquarius and the Sun enters Aries.
This year the city of Haridwar, along the Ganges, is playing host to the historic event over the course of several months.
