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.
No work or love will flourish out of guilt, fear, or hollowness of heart, just as no valid plans for the future can be made by those who have no capacity for living now.
When your eyes are functioning well you don't see your eyes. If your eyes are imperfect you see spots in front of them. That means there are some lesions in the retina or wherever, and because your eyes aren't working properly, you feel them. In the same way, you don't hear your ears. If you have a ringing in your ears it means there's something wrong with your ears. Therefore, if you do feel yourself, there must be something wrong with you. Whatever you have, the sensation of I is like spots in front of your eyes - it means something's wrong with your functioning.
A priest once quoted to me the Roman saying that a religion is dead when the priests laugh at each other across the altar. I always laugh at the altar, be it Christian, Hindu, or Buddhist, because real religion is the transformation of anxiety into laughter.
For unless one is able to live fully in the present, the future is a hoax. There is no point whatever in making plans for a future which you will never be able to enjoy. When your plans mature, you will still be living for some other future beyond. You will never, never be able to sit back with full contentment and say, "Now, I've arrived!" Your entire education has deprived you of this capacity because it was preparing you for the future, instead of showing you how to be alive now.
And although our bodies are bounded with skin, and we can differentiate between outside and inside, they cannot exist except in a certain kind of natural environment.
For every individual is a unique manifestation of the Whole, as every branch is a particular outreaching of the tree. To manifest individuality, every branch must have a sensitive connection with the tree, just as our independently moving and differentiated fingers must have a sensitive connection with the whole body. The point, which can hardly be repeated too often, is that differentiation is not separation.
The reason we have poverty is that we have no imagination. There are a great many people accumulating what they think is vast wealth, but it's only money... they don't know how to enjoy it, because they have no imagination.
We suffer from a hallucination, from a false and distorted sensation of our own existence as living organisms. Most of us have the sensation that "I myself" is a seperate center of feeling and action, living inside and bounded by the physical body-a center which "confronts" an "external" world of people and things, making contact through the senses with a universe both alien and strange.
The point, which can hardly be repeated too often, is that differentiation is not separation. The head and the feet are different, but not separate, and though man is not connected to the universe by exactly the same physical relation as branch to tree or feet to head, he is nonetheless connected - and by physical relations of fascinating complexity.
If happiness always depends on something expected in the future, we are chasing a will-o'-the-wisp that ever eludes our grasp, until the future, and ourselves, vanish into the abyss of death.
You know that if you get in the water and have nothing to hold on to, but try to behave as you would on dry land, you will drown. But if, on the other hand, you trust yourself to the water and let go, you will float. And this is exactly the situation of faith.
