I have to go away 
and see the sun set somewhere else. 
We all have the same sun 
but those eyes that see the setting sun are different. 
My eyes see not the same as theirs, therefore  
I have to go away and change my eyes 
to see their setting sun 
over warm blue oceans and fertile hills 
over cold dark mountains and arid waste 
over waving prairie and tranquil forest 
over glittering ice caps and sparkling seas. 
I have to go away 
but do not miss me as I go,  
for though I leave to chase the setting sun 
I will return to watch it rise again with you.
