Query: A Gem

This is a very strange and beautiful book in pictures. It reads like a dream if you tune in to it, and reveals very deep meanings about the relation between life and death, the human relation to the forces of nature, and time. Even though there are no words, it is possible to understand. If you get into it the symbols become more and more recognizable, and they begin to speak. the calendrical symbols and the spirit deities are completely recognizable. The sequences are all about times, and there is a big element about sacrifice. It has to do with the consequences of change; there is no life without death. The book has a very powerful image of life and death fused back to back that pretty much is the epitome of all the book is about. It's all about life and death in relation to time.
