What I term Zen, old Zen, the original face of Zen, new Zen, pure Zen, or Tantric Zen is - Zen in its essence.
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.
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.
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.
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.
Zen purposes to discipline the mind itself, to make it its own master, through an insight into its proper nature. This getting into the real nature of one's own mind or soul is the fundamental object of Zen Buddhism. Zen, therefore, is more than meditation and Dhyana in its ordinary sense. The discipline of Zen consists in opening the mental eye in order to look into the very reason of existence.
Zen is the enemy of analysis, the friend of intuition. The Zen artist understands the ends of his art intuitively, and the last thing he would do is create categories; the avowed purpose of Zen is to eliminate categories! The true Zen-man holds to the old Taoist proverb,
Those who know do not speak. Those who speak do not know.
The true purpose of Zen is to see things as they are, to observe things as they are, and to let everything go as it goes. Zen practice is to open up our small mind.
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."
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.
Throwing away Zen mind is correct Zen mind. Only keep the question, 'What is the best way of helping other people?'
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.
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.
If you have the sense of participation in sports or athletics, of being a player, then you are not really into the Zen mind. In Zen mind there is no sense of self in the play.
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.
