MAHA MRITYUNJAYA MANTRA

Om Trayambakam Yajamaha, Sugandhim Pushtivardhnam,
Urvaraka Miva Bandhanat, Mrityor Muksheeya Mamritat

Meaning:

I bow down to three-Eyed Lord Siva, Who is full of sweet fragrance,
Who nourishes well beings; May He free me from the bondage,
Of Samsara and Death, Just as the ripe cucumber is severed,
From the bondage to the Creeper! May I be fixed in Immortality!

Tryambakam : Tryambakam is Lord Siva. We devoutly utter, "Trayambakam" with the Bhavas, that Siva is the Lord of three Mothers of the Universe; That he is the Three eyed Lord; and beg for his grace to attain immortality.
In Vedic Paribhasha, the three mothers are Gayatri Chandas (Gnyana Sakti); Tristup Chandas (Icha Sakti); Jagat Chandas (Kriya Sakti);

Sugandhim: "Gandha", is smell or odour; it is sugar or vishama Gandha. 'Sugandha'-is fragrance that bestows Pusthi or growth or development on other things, and protects them from vikara;

Pushtivardhanam: Pushtivardhanam, is Lord Siva, who nourished well all beings, who bestows growth and development who develops small things from smaller to larger avastas, of diverse and numberless sizes, and to him we offer our prayers for immortality while we utter 'Pushtivardhanam'.
Yajamaha: "Yajamaha" indicates, the Union through the combination of the Three Saktis with Lord Siva who is Amara, and thereby enemy to Death, who is Prakash, thereby enemy to Darkness, who is staanu, and thereby enemy to Astirtva; who is supreme source of Amrita, Prakash, an Sthira Bhavas. Hence, we surrender ourselves completely to Lord Siva; and through surrender live in contact with and related to Him while we chant "Yajamaha"

Mrityor Bandhanat Urvaraka Miva Muksheeya: We thirst to be liberated from countless kinds of diseases; from Agnyana, from numerous diverse forms and durations of births and deaths; and to conquer Death.
The attainment of Mukti or freedom from the wheel of births and deaths is the Aim and Goal of the Aspirant who chants this Mantra; so he prays to Lord Siva to liberate him from Death for the sake of immortality, even as the cucumber is freed without effort, from its bondage to the creeper.

Mamritat Muksheeya:
Relationship is established by the aspirant with Brahman, who is Amara, Prakasa, Nitya, Ekaakaara; Thereby, the Aspirant also becomes Amara Prakasa and enjoys Avichanna relationship with Brahman (Lord Siva) who is Amara; Prakasa, Susthira Swaroopa. Thus, through fervent constant Japa of this Mantra, the Aspirant attains the Stairya of the Sanatana Relationship between the Jeeva and Paramatma and Atmashema.
