I ... had what Kierkegaard called 'the sickness of infinitude,' wandering from one path to another with no real recognition that I was embarked upon a search, and scarcely a clue as to what I might be after. I only knew that at the bottom of each breath there was a hollow place that needed to be filled.

Soon the child’s clear eye is clouded over by ideas and opinions, preconceptions, and abstractions. Simple free being becomes encrusted with the burdensome armor of the ego. Not until years later does an instinct come that a vital sense of mystery has been withdrawn. The sun glints through the pines and the heart is pierced in a moment of beauty and strange pain, like a memory of paradise. After that day, we become seekers.

Simplicity is the whole secret of well-being.

There's an elegiac quality in watching [American wilderness] go, because it's our own myth, the American frontier, that's deteriorating before our eyes. I feel a deep sorrow that my kids will never get to see what I've seen, and their kids will see nothing; there's a deep sadness whenever I look at nature now.

Zen is really just a reminder to stay alive and to be awake. We tend to daydream all the time, speculating about the future and dwelling on the past. Zen practice is about appreciating your life in this moment. If you are truly aware of five minutes a day, then you are doing pretty well. We are beset by both the future and the past, and there is no reality apart from the here and now.

Amazingly, we take for granted that instinct for survival, fear of death, must separate us from the happiness of pure and uninterpreted experience, in which body, mind, and nature are the same. This retreat from wonder, the backing away like lobsters into safe crannies, the desperate instinct that our life passes unlived, is reflected in proliferation without joy, corrosive money rot, the gross befouling of the earth and air and water from which we came.
