# Dadhici’s Sacrifice The Lord regretted that their prayers were not spiritually aimed, but He nevertheless assisted them in killing Vritrasura. He told them to request Dadhici Muni for the bones of his own body, which would be used to create a special thunderbolt weapon to kill Vritrasura. When the demigods approached Dadhici he readily agreed, understanding the inevitable death of the material body and the higher cause that he could serve by making this sacrifice. How magnanimous and noble Dadhici was! This body, he said, is meant for the welfare work of others. Situating himself in a mystic trance, Dadhici shed his gross body and then engaged his soul at the lotus feet of the Supreme Personality of Godhead. With the help of Visvakarma, the demigods then prepared a thunderbolt from Dadhici’s bones. Armed with the thunderbolt weapon, they prepared themselves to fight and mounted the backs of elephants. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
