Poem I wrote... quick-unedited

Man, like a tree
lifts up his urgent arms
to heaven
and, like a tree
his roots reach out to find and to explore
the deepest regions of the mind.
If, like a tree, a man
should shelter in his day
the other living things of earth:
if underneath his shade
the twigs of knowledge
and the leaves of joy
should come to birth:
then haply, like a tree,
a man may fall
and sleep within his roots
and, like a tree,
be known by his fruits.
