My mind wandered to far away Nda za gko to the lovely alpine meadows on the Likiang Snow Range [Yulong Xue Shan] where reigns eternal peace. In spite of all the glitter and good food and comfort, etc on this boat it is all artificial. Here one looses [sic] contact with the great spirit of nature. I am longing for a quiet spot where I can stay with my Nakhi boys and live in peace, where I shall not have to move again except when the great day comes when I shall go to my eternal rest. When I behold the women on this ship, artificial, all flesh and no soul I shudder when I think what their life must be; a decorated painted shell ever moving but getting nowhere except farther away from what should be the real life of contemplation and unselfishness.” (pp.152-153)
