Here's a touching poem by ee cummings (real name Edward Estlin Cummings, but often signed as shown before), titled i carry your heart with me. (NOTE: All spaces and spellings are of Cummings, not mine.)
Unfortuantly, Blogger's being a little weird right now and so I had to take a screen shot of the poem. Click on the picture below to maximize the poem.
I like the last stanza the best..."the root of the root and the bud of the bud."
Isn't that so touching?
