Wabi means spare, impoverished; simple and functional. It connotes a transcendence of fad and fashion. The spirit of wabi imbues all the Zen arts, from calligraphy to karate, from the tea ceremony to Zen archery.
What I term Zen, old Zen, the original face of Zen, new Zen, pure Zen, or Tantric Zen is - Zen in its essence.
Zen is the spirit of a man. Zen believes in his inner purity and goodness. Whatever is superadded or violently torn away, injures the wholesomeness of the spirit. Zen, therefore, is emphatically against all religious conventionalism.
Tantric Zen is for someone who is really broad-minded. It is Bodhidharma's Zen, your Zen, my Zen. Which doesn't mean I have a problem with Japanese Zen. Most Japanese Zen is minding your p's and q's.
The great achievement of Zen Buddhism, and all of its cultural expressions in painting or the tea ceremony or rock gardens, is a rejection of earlier Buddhist ideas which were dependent
upon narrative - all the mythological creatures that populate the Buddhist galaxy. Zen insisted on the real located in nature.
And finally, be assured that Zen asks nothing even as it promises nothing. One can be a Protestant Zen Buddhist, a Catholic Zen Buddhist or a Jewish Zen Buddhist. Zen is a quiet thing. It listens.
Tantric Zen is the original Zen, Zen without rules, Zen without form. Zen can certainly take rules and form. So Tantric Zen might have some rules and form, but it would remain formless even though it had rules and form.
Now when I speak about Zen, I have a problem, in the sense that the Zen of today has lost the essence, in my estimation, of what I call "old Zen."
Zen is really extraordinarily simple as long as one doesn't try to be cute about it or beat around the bush! Zen is simply the sensation and the clear understanding ... that there is behind the multiplicity of events and creatures in this universe simply one energy -- and it appears as you, and everything is it. The practice of Zen is to understand that one energy so as to "feel it in your bones.
I snap at people I love all the time, and that makes me feel bad about myself. I want to be Zen. I am so not Zen. Whatever Zen is, I'm the opposite of it.
If I am asked If I am asked, then, what Zen teaches, I would answer, Zen teaches nothing. Whatever teachings there are in Zen, they come out of one's own mind. We teach ourselves; Zen merely points the way.
There are two primary ways of studying Zen. Either an individual will enter into a Zen monastery and study with a Zen master there, or they will study with a Zen master who lives in the contemporary world.
Different schools of Zen have evolved, principally the Rinzai and Soto orders. A whole hierarchy has developed for the teaching and practice of Zen. Zen has become, to a certain degree, institutionalized.
Zen is a very quick path. Zen is the path of meditation. The word Zen means emptiness or fullness, meditation. Meditation is the quickest path to enlightenment.
The claim of the Zen followers that they are transmitting the essence of Buddhism is based on their belief that Zen takes hold of the enlivening spirit of the Buddha, stripped of all its historical and doctrinal garments.
So the most difficult thing is always to keep your beginner's mind. There is no need to have a deep understanding of Zen. Even though you read much Zen literature, you must read each sentence with a fresh mind. You should not say, "I know what Zen is," or "I have attained enlightenment." This is also the real secret of the arts: always be a beginner. Be very very careful about this point. If you start to practice zazen, you will begin to appreciate your beginner's mind. It is the secret of Zen practice.
When I say that Zen is life, I mean that Zen is not to be confined within conceptualization, that Zen is what makes conceptualization possible.
