One of the chief devas.

In the Tevijja Sutta DN.i.244 he is mentioned with Indra, Soma, Varuṇa, Pajāpati and Brahmā, as being invoked by the brahmins.

He was in the battle of the devas against the Asuras and led a section of the deva host. Indra tells the devas that if, during the struggle, they felt faint-hearted, they should look at the crest of his own banner or at that of Pajāpati, Varuṇa or Īsāna, and their fear would disappear. SN.i.219
