What is the legend behind offering hair or Veni at Prayagraj?

One legend connects it to Savitri, who is said to have offered a part of her hair (symbolically represented) praying for her husband’s life. Another belief stems from appeasing the river goddesses Ganga, Yamuna, and Saraswati through this offering. The connection to Lord Veni Madhav also plays a role, with the belief that he blesses couples performing this ritual at the Sangam. The symbolism links the three river streams to the three hair strands, making the offering unique to this location.
