Hardwar, is situated on the foothills of Shivaliks.
It is here that the river Ganga, coming down from the gigantic Himalayas,
touches the plains. Haridwar is the first place where the river
meets the plains

.
Also known as Mayapuri, Gangadwar, Tapovan and Mokshadwar in the
ancient scriptures, Haridwar is a city with immense religious significance
and a major pilgrimage town for the Hindus. It is among the seven
sacred cities of India and one of the four holy sites for Kumbh
Mela. It also finds importance as one of the major Shaktipeeths.
The Mythological Origin
The historical relevance of the Kumbh Mela goes back to the time
when the Amritkalasha (pot of amrit) was retrieved from the Samudramanthan
(churning of the ocean). A great fight followed between the gods
and the demons, to take possession of the pot of amrit. During
this tussle, a few drops of nectar fell at four places: Prayag
(Allahabad), Haridwar, Nasik and Ujjain. To commemorate this holy
event, Hindus from all over the country come together for to take
a holy dip in the mighty Ganga.
The Planetary Positioning
The astrological date for Kumbh at Haridwar falls when Venus and
Jupiter coincide with Aquarius and the Sun enters Aries. This
planetary position is said to medicate the waters of the Ganga
and turn it into nectar. Apart from Kumbh, Ardh Kumb Mela is also
held here,every six years.
