19) *Agastya and the River Kāverī*. Once Sūrapadmā, an Asura (demon) drove the Gods out from heaven. Indra came to Śiyāli a place in the district of Tañjāvūr (Tanjore) and began to do penance to please Śiva. Rain was completely stopped. Agastya had compressed the river Kāverī and held the water in his waterpot. Gaṇapati having come to know of this, came in the form of a crow and toppled the waterpot. Agastya got angry and ran after the crow, which immediately assumed the form of a boy. Agastya caught hold of him. The boy instantly revealed himself as Subrahmaṇya and granted Agastya a boon. "Your waterpot will always be full". Since then there had never been shortage of water in the Kāverī. (Skanda Purāṇa).
