According to astrologers, the 'Kumbh Fair' takes place when the planet Jupiter enters Aquarius and the Sun enters Aries. According to mythology, 'Devas' (Gods) and 'Asuras' (Demons) churned the ocean to obtain Nectar and when the coveted 'Kumbha' (pitcher) of Nectar (Amrita) which gave immortality was obtained from the depths of ocean, one of the 'Devas' whisked away the 'Kumbha' from the 'Asuras' and evading from the 'Asuras', stopped at four places viz. Haridwar, Allahabad (Prayag), Nasik and Ujjain before he finally arrived into the safety of heaven. A few drops of Nectar are supposed to have spilled over on the water at these four places and sages, saints and pilgrims started periodically to flock to each of these 'Tirthas' to celebrate the divine event. In fact , it is a unique event that blends religious and social features alike.
