One day's exposure to mountains is better than a cartload of books.
How glorious a greeting the sun gives the mountains!
Books are but stepping stones to show you where other minds have been.
As long as I live, I'll hear waterfalls and birds and winds sing. I'll interpret the rocks, learn the language of flood, storm, and the avalanche. I'll acquaint myself with the glaciers and wild gardens, and get as near the heart of the world as I can".
A little pure wildness is the one great present want, both of men and sheep.
Lie down among the pines for a while, then get to plain pure white love-work ... to help humanity and other mortals and the Lord.
