In Hindu tradition Triveni Sangam is the "confluence" of three rivers, two physical rivers Ganges, Yamuna, and the invisible or mythic Saraswati River. The site is in Prayag, India. A place of religious importance and the site for historic Kumbh Mela held every 12 years, over the years it has also been the site of immersion of ashes of several national leaders, including Mahatma Gandhi in 1948.
Sangama is the Sanskrit word for confluence. The Triveni Sangam in Allahabad is a confluence of 3 rivers, the Ganges, Yamuna, and Saraswati. Of these three, the river Saraswati is invisible and is said to flow underground and join the other two rivers from below. The point of confluence is a sacred place for Hindus. A bath here is said to wash away all of one's sins and free one from the cycle of rebirth. Here the muddy and pale-yellow waters of the Ganges merge with the blue waters of Yamuna. While the Ganges is only 4 feet deep, the Yamuna is 40 feet deep near the point of their nexus. The river Yamuna merges into the Ganges at this point and the Ganges continues on until it meets the sea at the Bay of Bengal. At the confluence of these two great Indian rivers, where the invisible Saraswati conjoins them, many tirtha yatris take boats to bathe from platforms erected in the Sangam. This, together with the migratory birds give a picturesque look to the river during the Kumbha Mela, in the month of January. It is believed that all the gods come in human form to take a dip at the sangam and expiate their sins.
This was the river where an earlier Prime minister of India, Indira Gandhi used to come for a holy dip. On the bank of the Ganges at Daraganj, just before the confluence of ganga and Yamuna, the well known statistician Ravindra Khattree spent his early years when he attended Ewing Christian College, situated on the bank of Yamuna few miles before the confluence. On the other bank of the river Ganges at Arail is located the Maharshi Institute of Management, named for Maharshi Mahesh Yogi who was a student at the University of Allahabad. The Harish Chandra Research Institute, named after the famous mathematician Harish Chandra from Allahabad, is also located on the same side - in the village of Jhusi.
The Triveni Sangam is believed to be the same place where drops of Nectar fell from the pitcher, from the hands of the Gods. So it is believed that a bath in the Sangam will wash away all one's sins and will clear the way to heaven. Devout Hindus from all over India come to this sacred pilgrimage point to offer prayers and take a dip in the holy waters. The sacred Kumbh Mela is held every 12 years on the banks of the Sangam. According to myth, the Prakrista Yajna was performed here by Lord Brahma. That is why Allahbad was known as Prayag in ancient times. Allahabad (Prayag) is also called Tirtha-Raja (Prayag Raj), king of all holy places. It is said that Lord Rama visited Allahabad when he was in exile
