 According to another version this is the "Bija mantra" as revealed to Rishi Kahola that was given by Lord Shiva to sage Sukracharya, who taught it to Rishi Dadhichi, who gave it to King Kshuva, through whom it reached the Shiva Purana.This mantra is also called the "Rudra mantra", referring to the furious aspect of Shiva; "the Tryambakam mantra", alluding to Shiva's three eyes; and it is sometimes known as the "Mrita-Sanjivini" mantra because it is a component of the "life-restoring" practice given to the primordial sage Sukracharya after he had completed an exhausting period of austerity.Its "Devata" (patron deity) is Rudra, i.e., Shiva in his fiercest and most destructive "roopa" or aspect.
