The great mantra dedicated to Shiva as Mrityunjaya is found in the Rig Veda. It is called the Maha Mrityunjaya mantra, the Great Death-Conquering 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 Shukra after he had completed an exhausting period of austerity. The Maha Mrityunjaya mantra is hailed by the sages as the heart of the Veda. Along with the Gayatri mantra it holds the highest place among the many mantras used for contemplation and meditation.
