The Rohini River is one of the holiest and most revered rivers in Buddhist scriptures. The river originates from the Siwalik hills and flows through a dense evergreen forest and cultivated plains. It irrigates a large area of land in the region. Once, during a long drought, the Sakyas and the Koliyas were about to fight a battle for its water. The dispute arose between the two states over the sharing of water of a dam constructed close to the river. As the princes and soldiers from both sides had gathered for a battle, Lord Sakyamuni Buddha was informed about it. He traveled from Vaisali and convinced the hostile groups not to fight; telling them blood was thicker than water. The two confronting sides then, calmed down, thereafter shared the water without losing their temper. Harmony was restored and peace prevailed in the region. Some 500 Sakyas and Koliyas converted into Buddhist upon hearing the teachings of Lord Sakyamuni Buddha.
