Rudra, which in Sanskrit means "Howler," is a god of the storm, the hunt, death, Nature and the Wind in the Vedas. Rudra is thought to be an early form of Shiva, the lord of destruction in Hinduism, and a name of Shiva in the Shiva Sahasranama.
Rudra has arrows which cause disease in whomever he hits whether it be a god, human or animal. With Diti he is the father of the Maruts. The famous hymn, Shri Rudram is a Vedic Mantra that is still chanted today.
