"First there is a mountain. Then there is no mountain. Then there is."

• Donovan, 1967

Adapted from:

"Before I had studied Ch'an (Zen) 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."

Qingyuan Weixin, 9th Century Buddhist Monk
