It is a special kind of enlightenment to have this feeling that the usual, the way things normally are, is odduncanny and highly improbable. G.K.Chesterton once said that it is one thing to be amazed at gorgon or a griffin, creatures which do not exist; but it is quite another and much higher thing to be amazed at a rhinoceros or a giraffe, creatures which do exist and look as if they don't. This feeling of universal oddity includes a basic and intense wondering about the sense of things.
There is nothing wrong with meditating just to meditate, in the same way that you listen to music just for the music. If you go to concerts to "get culture" or to improve your mind, you will sit there as deaf as a doorpost.
In other words, a person who is fanatic in matters of religion, and clings to certain ideas about the nature of God and the universe, becomes a person who has no faith at all.
It is the seeker, who understands there is more than what meets the eye, who is not afraid and makes the choice to go into the unknown. The process of awaking has begun, the discovery is underway.
Essentially Satori is a sudden experience, and it is often described as a "turning over" of the mind, just as a pair of scales will suddenly turn over when a sufficient amount of material has been poured into one pan to overbalance the weight in the other. Hence it is an experience which generally occurs after a long and concentrated effort to discover the meaning of Zen.
The problem comes up because we ask the question in the wrong way. We supposed that solids were one thing and space quite another, or just nothing whatever. Then it appeared that space was no mere nothing, because solids couldn't do without it. But the mistake in the beginning was to think of solids and space as two different things, instead of as two aspects of the same thing. The point is that they are different but inseparable, like the front end and the rear end of a cat. Cut them apart, and the cat dies.
What you do is what the whole universe is doing at the place you call "here and now," and you are something the whole universe is doing in the same way that a wave is something that the whole ocean is doing... The real you is not a puppet which life pushes around. The real deep-down you is the whole universe.
