Thanks to Clark Boyd at The World for cheering me up with this one.
Update: The end credits say the song text is an adaptation of the poem Stream of Life by Rabindranath Tagore.
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.
Rabindranath Tagore
