Can You please explain the meaning of Mahamrityunjaya Mantra?

[Shri Martin Evind asked: Dear Swami, would You please explain Mahāmrityunjaya Mantra and is repeating this mantra (knowing the English translation) appropriate to use with sincere devotion for physical and mental healing of others and oneself? Pranams, Martin Evind California USA]

Swami Replied:- We do not believe in mantras. Mantra means any line of prose or poetry or song on God that attracts your mind spontaneously to repeat again and again without aspiration for any fruit from God. God will increase the longevity of a person without any request through mantra provided the devotee is in the path of spiritual line and if the devotee requires some more life time to reach the spiritual goal. God shall do anything by His will and no mantra can bind Him to perform in the miracle forcibly.
