"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."
