Gaṇeśakuṇḍa is a sacred kuṇḍa (pool) and tīrtha on the river Narmadā. It came into being in Dvāpara Yuga, when the body of the infant Gajānana touched the Narmadā. The daitya Sindūra had thrown the newborn child into the river. The ṛshi Pārāśara found the infant near this spot, took him to his āśrama and raised him.

Creation

Sindūra tried to destroy the infant Gajānana at Māhishmatī. When he tried to throw the child into the ocean, the infant became too heavy to move. So Sindūra threw the divine child into the Narmadā river instead. The infant fell into the Narmadā, or near it, close to a forest where munis lived.

The moment the infant’s body touched the Narmadā, Gaṇeśakuṇḍa came into being. The touch of Gajānana’s body with the river water made that spot a tīrtha. (Gaṇeśa Purāṇa, Krīḍā Khaṇḍa, Chapter 132)

Pārāśara finds the infant

The ṛshi Pārāśara found the infant in the forest near this spot. He knew the divine nature of the child and brought him to his āśrama. Pārāśara’s wife nursed the infant and cared for him.

In Pārāśara’s āśrama the infant Gajānana later tamed the mūshaka (mouse) and gained it as his eternal vehicle. (Gaṇeśa Purāṇa, Krīḍā Khaṇḍa, Chapters 132–133)
