My acquaintance currently traveling in Tibet, continues to send on-the-road messages.
Today he talked about his wife having a bout of altitude sickness and his encounter with oriental approaches to medicine, first hand.
He said that he attended a lecture featuring the thanka below, said to be based on charts developed 700 years ago.
He says that the lecturer said that this tree depicts the field of medicine, with the left side outlining aspects of " healthy physiology" and the right side devoted to "pathology."
At last: a textile design we may be able to interpret at some level.
