This old chair.
The weather can't make up its mind.
The wood stove grows cold

The problem haiku attempts to solve is the same problem posed by living life. How to focus in on the now moments. How can it blend conscious thought and vivid tactical, visceral experiences into a language that doesn't trigger just more thoughts without pointing anything out.

Sometimes silence is what you need to express this 'pointing out.' There needs to be space in the haiku for silence to occur. It is important to leave plenty of space for the silence of the moment. The haiku is written in one moment and read in another. Dogen would question this but it would be good to "act as if" there were two moments.
