Earth's Valentine

Why make a physical body
And go to all that pain and trouble
Of planning and redacting
If not to get something done
Why use emotions and will
And a few simple ideas
To develop organs and blood
Out of the empty marrow of bones
If not to realize something
Not otherwise conceivable
That our bodies are not our own
That we merely have the loan
Of these fine arms and eager legs
And leave to the earth their forms
