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 Not until years later does an instinct come that a vital sense of mystery has been withdrawn.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.

How could I say that I wished to penetrate the secrets of the mountains in search of something still unknown that, like the yeti, might well be missed for the very fact of searching?

The concept of conservation is a far truer sign of civilization than that spoilation of a continent which we once confused with progress.

You see ... a man like me, a cautious man, has his life all figured out according to a pattern, and then the pattern flies apart. You run around for quite a while trying to repair it, until one day you straighten up again with an armful of broken pieces, and you see that the world has gone on without you and you can never catch up with your old life, and you must begin all over again.

If we were doomed to live forever, we would scarcely be aware of the beauty around us.

In the clearness of this Himalayan air, mountains draw near, and in such splendor, tears come quietly to my eyes and cool on my sunburned cheeks. this is not mere soft-mindedness, nor am I all that silly with the altitude. My head has cleared in these weeks free of intrusions- mail, telephones, people and their needs- and I respond to things spontaneously, without defensive or self-conscious screens. Still, all this feeling is astonishing: not so long ago I could say truthfully that I had not shed a tear in twenty years.

The ancient intuition that all matter, all "reality," is energy, that all phenomena, including time and space, are mere crystallizations of mind, is an idea with which few physicists have quarreled since the theory of relativity first called into question the separate identities of energy and matter. Today most scientists would agree with the ancient Hindus that nothing exists or is destroyed, things merely change shape or form; that matter is insubstantial in origin, a temporary aggregate of he pervasive energy that animates the electron.
