I just realized that the song which accompanies Matt Harding's 2008 video is an adaptation of Rabindranath Tagore's "Stream of Life":

Stream of Life 

The same stream of life that runs through my veins night and day

runs through the world and dances in rhythmic measures. 

It is the same life that shoots in joy through the dust of the earth

in numberless blades of grass

and breaks into tumultuous waves of leaves and flowers. 

It is the same life that is rocked in the ocean-cradle of birth

and of death, in ebb and in flow. 

I feel my limbs are made glorious by the touch of this world of life.

And my pride is from the life-throb of ages dancing in my blood this moment.
