Let's see if I can try this....
Buddhism is the method to awaken oneself as taught by the One who has been awakened.
I really like the descriptions given before my post as well.
I also like the last sentence in the first paragraph in the Wiki for Buddhism (http://en.wikipedia.org/wiki/Buddhism
) which says
Buddhism is traditionally conceived as a path of liberation attained through insight into the ultimate nature of reality.
although if I were to use this description personally, I would change the sixth word from the indefinite article to the definite article.
