Sangam River

Sacred Sangam:
Sangam is the confluence of three of the holiest rivers in Hindu mythology - Ganga, Yamuna and the mythical Saraswati. At the Sangam, the waters of the Ganges and the Yamuna can be distinctly seen to merge into one. At Allahabad, the meeting point of the rivers is believed to have great soul cleansing powers and is a major pilgrimage site. It is even more holy because the invisible Saraswati river is supposed to the join the Ganga and Yamuna at this point.

Legendry Saga:
According to mythology, the gods and demons once churned the oceans to retrieve a pitcher containing the nectar of immortality - amrit -- after which a struggle ensued between the two to wrest control of this pitcher. It is said that during the scuffle, a few drops of amrit were spilled at places, making them hallowed and sacred. The waters at the Sangam are believed to have received the amrit too and a dip in these holy waters during the Kumbh is believed to cleanse and purify the soul.
