<blockquote>
<p>Before I had studied Chan for thirty years, I saw mountains as
mountains, and rivers as rivers. When I arrived at a more intimate
knowledge, I came to the point where I saw that mountains are not
mountains, and rivers are not rivers. But now that I have got its very
substance I am at rest. For it's just that I see mountains once again
as mountains, and rivers once again as rivers.</p>
