Satori is the spiritual goal of Zen Buddhism… It is a key concept in Zen. Whether it comes to you suddenly seemingly out of nowhere…or after an undetermined passage of time centered around years of intense study and meditation…or after forty unrelenting years as with the Buddha’s brother Ananda, there can be no Zen without that which has come to be called Satori.

Satori roughly translates into individual Enlightenment, or a flash of sudden awareness. ~ http://sped2work.tripod.com/satori.html

Satori is sudden enlightenment
and a state of consciousness
attained by intuitive illumination
representing the spiritual goal
of Zen Buddhism. In every corner
of Earth the awareness of a Greater Power
has led to similar understandings
of something beyond.
Whether we speak of Holy Spirit,
Jesus, omnipotence, divine order…
We can define and name our own
Higher Power, and the better acquainted
the two of us come the more peobable
we will find our own sudden enlightenment.
Praise be to that Power!
