 "The Immaculate Crystal Garland" () describes the origin of amrita in a version of the samudra manthana legend retold in Buddhist terms.In this Vajrayana version, the monster Rahu steals the amrita and is blasted by Vajrapani's thunderbolt.As Rahu has already drunk the amrita he cannot die, but his blood, dripping onto the surface of this earth, causes all kinds of medicinal plants to grow.
