Indra’s troops (ganas), storm deities, also called Maruts.
Diti asked Kashyapa for a son who could destroy Indra. Indra went into Diti’s womb, and divided the fetus into 49 parts. The parts screamed, Indra shouted: ‚Ma ruda‘ – don’t scream. When they were born he called them Maruts. In this context Indra is known as Gotrabhit ‚one who kills someone from his lineage (gotra)‘.
