The Sacrifice of Sage Dadhichi and the Forging of the Vajra
When the demon Vritra stole the world's waters and became invincible to all known weapons, the gods sought the help of the sage Dadhichi. Realizing that only a weapon made from the bones of a pure soul could defeat the evil, Dadhichi willingly gave up his life. His sacrifice allowed Indra to forge the Vajra, defeat Vritra, and restore life to the parched universe.
