The soul is something which contains the body. The body doesn't contain the soul. The soul, if we put it into modern language, is the entire complex of relationships in whose context this organism exists.
For when you see that the universe cannot be distinguished from how you act upon it, there is neither fate nor free will, self nor other. There is simply one all-inclusive Happening, in which your personal sensation of being alive occurs in just the same way as the river flowing and the stars shining far out in space. There is no question of submitting or accepting or going with it, for what happens in and as you is no different from what happens as it.
But nirvana is a radical transformation of how it feels to be alive: it feels as if everything were myself, or as if everything---including "my" thoughts and actions---were happening of itself. There are still efforts, choices, and decisions, but not the sense that "I make them"; they arise of themselves in relation to circumstances. This is therefore to feel life, not as an encounter between subject and object, but as a polarized field where the contest of opposites has become the play of opposites.
That's a waste of time. If you really understand Zen... you can use any book. You could use the Bible. You could use Alice in Wonderland. You could use the dictionary, because... the sound of the rain needs no translation.
To be alive spiritually man must have union with God and must be conscious of it. Apart from this union his religious life will be an empty drudgery, a mere imitation of true spirituality.
There is no formula for generating the authentic warmth of love. It cannot be copied. You cannot talk yourself into it or rouse it by straining at the emotions or by dedicating yourself solemnly to the service of mankind. Everyone has love, but it can only come out when he is convinced of the impossibility and the frustration of trying to love himself. This conviction will not come through condemnations, through hating oneself, through calling self love bad names in the universe. It comes only in the awareness that one has no self to love.
The Tao belongs neither to knowing nor not knowing. Knowing is false understanding; not knowing is blind ignorance. If you really understand the Tao beyond doubt, it's like the empty sky. Why drag in right and wrong?
We are the eyes of the cosmos. So that in a way, when you look deeply into somebody's eyes, you're looking deep into yourself, and the other person is looking deeply into the same self.
So many people of wealth understand much more about making and saving money than about using and enjoying it. They fail to live because they are always preparing to live.
Real travel requires a maximum of unscheduled wandering, for there is no other way of discovering surprises and marvels, which, as I see it, is the only good reason for not staying at home.
