Legend of Indra
According to the legends Indra, the Pauranic (according to the Hindu
puranas) King of the Heavens, received setbacks at the hands of the
demon king (the Daitya raja). After these reverses, Indra sought the
advice of Brihaspati (the Devaguru). On the advice of the Devaguru,
Indrani (the consort of Indra) tied silken amulets (Raksha Bandhan) on
Indra wrists, on the auspicious occasion of Shravan Poornima. Indra,
thus, defeated the Daitya-Raja (demon king) and re-established control
over his celestial dwelling.
