When the Asvini-kumaras beg for Dadhyanca’s body on your behalf, he will surely give it because of affection. Do not doubt this, for Dadhyanca is very experienced in religious understanding. When Dadhyanca awards you his body, Visvakarma will prepare a thunderbolt from his bones. This thunderbolt will certainly kill Vrtrasura because it will be invested with My power.
