feet sans shoes

caress autumn soil

cool and dry

The 3-5-3 is really an American Haiku form which is intentionally crafted to address the change in feel when one reads a 5-7-5 one in English. Japanese and English are quite different in their phonetics and feeling, so the 3-5-3 ones in English come closer to the terse feel of the 5-7-5 Japanese ones. Do correct me if I'm wrong someone. :)  And there is freedom for poetic license because I've read Haiku by Zen masters like Basho, Issa and Chiyojo which have an added syllable in one of the lines to preserve the poetry of the words.

Thanks for your explanatino of Renga. I was curious too, about what it was. :)
