In Hindu tradition Triveni Sangam is the "confluence" of three rivers. Sangama is the Sanskrit word for confluence. The point of confluence is a sacred place for Hindus. A bath here is said to flush away all of one's sins and free one from the cycle of rebirth. One such Triveni Sangam, in Prayag (Allahabad) has two physical rivers — Ganges and Yamuna — and the invisible 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.
Prayag is one of the ancient pilgrimage centers of India, and it represents the confluence of the rivers Yamuna and Ganga, near (in) the city of Allahabad in Uttar Pradesh.
