On Kensho Being Available to All Faiths
Zen: The Authentic Gate
Text
I have come to the conclusion that Zen is not a religion in the sense that the term is popularly understood. It has no special doctrine or philosophy, no creeds or dogmas, no ritual or liturgy, and no prescribed form of worship. Kensho—seeing into one's own nature—is available to people of all faiths. A Christian can practice Zen and deepen their Christianity. A Buddhist can practice Zen and deepen their Buddhism. Zen is the practice of coming to the experience that lies at the root of all religions.
