Analysis of Of a vast rainbow

A spark in the dark
As a light and star
Shot forth a scheme
Of colors and code
Of a vast rainbow
With water and spirit
Lifted in the midst
As the light revolves
Around us As a friend
In the end of time
As it is endless
Of friends with no end
And a family tree
Of geneology and a sea
Of remembrance
And forgetfulness
As eternal as the sun
And an end like the moon
As shadows loom
Over us as a guest
That never leaves
But remains a friend
Without enemies or an end
