A white bird flying at day
Or a black bird flying at night
Or a black bird flying at day
Or a white bird flying at night
Black and white, black over white 
Oh,my Lord, how painful can be 
This need of touch in his absence
White and black, white over black
Oh,my Lord, how painful can be 
This absence of his touch
Black penetrating white
And white penetrating black
Never finding the gray.
