The Falgu River is steeped in Hindu mythology and has been mentioned in various ancient texts. It is believed that Lord Rama, Sita, and Lakshmana visited the banks of this river during their exile. A famous legend tells of Sita Mata performing Pind Daan for King Dasharatha here when Lord Rama was away. When no one else was available to witness the ritual, the river itself is said to have testified—but later denied the event to Lord Rama. In response, Sita cursed the river to remain dry for most of the year. To this day, the river appears mostly sandy on the surface, despite water flowing underground.

Over the centuries, the river became a major site for ancestral rituals, especially during Pitru Paksha. It flows through Gaya and Bodhgaya, areas associated with Lord Vishnu and Lord Buddha. Even in its dryness, the Falgu River flows through the heart of India’s religious consciousness, carrying with it the spiritual legacy of generations.
