What is Zen? It’s both something we are—our true nature expressing itself moment by moment—and something we do—a disciplined practice through which we can realize the joy of being. It is not a belief system to which one converts. There is no dogma or doctrine. Zen is the direct experience of what we might call ultimate reality, or the absolute, yet it is not separate from the ordinary, the relative. This direct experience is our birthright. The practice of zazen—meditation—is a way of realizing the non-dualistic, vibrant, subtle, and interconnected nature of all life.
