The Lord Mahamrityunjaya mantra is to be found in the oldest of the Vedas, the Rigveda. It espouses in full the glory of the Lord, also known as Lord Trayambaka. He is the three- (tri) eyed (ambaka) one, the third having spouted from the deepest realms of contemplation (samadhi). His legs are gathered in the poorna-padmasana, the perfection of which is indicative of siddhi (accomplishment) in every other asana known to man. Siddhi in this asana paves the way for the stages of pranayama-dharana-dhyana-samadhi. The murti you see on this page is the very image of the highest form of samadhi (contemplation).
The shashtabhujadhari (six-armed) Deva bears in His posteriormost arms a pair of amrtakalasha (pots of nectar). These He holds over His finely sculpted jataein (dreadlocks). From the trishool and the tigerskin loincloth and asana (mat), to the snakes wound around His neck and ankles, Lord Mahamrityunjaya bears all the hallmarks of the primal Shiva iconography.
