The poem in search of its poet

Came across this beautiful poem at the entrance of Research and Development facility of Nicholas Piramal at Mumbai day before yesterday as we went to take kids for a science trip to the facility.

The poet's name was not mentioned. Did some search on the internet and got an indirect reference of this poem by Tagore who stated that this poem was translated from a peom written by a woman from medieval India.  Now to me its like a poem which is unconcerned about the search for its creator.

I salute the Life which is like a sprouting seed,
With its one arm upraised in the air, and the other down in the soil;
The Life which is one in its outer form and its inner sap;
The Life that ever appears yet ever eludes.
The Life that comes I salute; and the Life that goes;
I salute the Life that is revealed and that is hidden;
I salute the Life in suspense, standing still like a mountain, And the Life of the surging sea of fire;
The Life that is tender like a lotus, and hard like a thunderbolt.
I salute the Life which is of the mind, with its one side in the dark and the other in the light;
I salute the Life in the house and the Life abroad in the unknown,
The Life full of joy and the Life weary with its pains,
The Life eternally moving, rocking the world into stillness,
The Life deep and silent, breaking out into roaring waves.

Life has continued to mesmerise people since ages and it will continue to do that for ever. Love the way this mystery envelopes us and also defines our journey on this planet.
