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?
Existence is only in the present. Mind is never in the present. In fact, the moment you are in the present, there is no mind in you, there is great silence. The whole sky of your inner being is without thoughts, without clouds. I call this the state of no-mind. Only in this state of no-mind do you meet existence. And that meeting is the ultimate ecstasy. Once you have tasted it, you will never bother about the future.
If I could dwell where Israfel hath dwelt and he where I he might not sing so wildly well a mortal melody while a bolder note then this might swell from my lyre in the sky.
