Via Daily Dharma / The Evolution of Understanding:

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.

—Qingyuan Weixin, "First There Is a Mountain (Then There Is No Mountain)"
