Take your fingers and dry them. Then dry them again. This is what you do when you are in worship. Once you go into your place of worship, and again before you leave. You have really sweaty fingers, and you can't worship anyone or anything if you have wet hands. So you dry them!

Once you're dry and in wherever your worship is, you begin with a haiku (はい). Really all places of worship have their own version of the haiku, and heck, the 5-7-5 rule is just a guideline, so everyone is doing it pretty close to right anyway.
