Besides the Soto and Rinzai schools in Japan, there is also Obaku, http://www.angelfire.com/indie/cameroonsudialmac/ObakuZen.html
which is more similar to the Zen schools outside of Japan. They use the Amida Buddha symbolism, which has been largely dropped from Soto and Rinzai.
Do not forget the Budha Bing
There are an eternity of eternities.
You help yourself by helping others;
you help others by helping yourself.
I am you?
