The book is called Food of the Gods by Jasmuheen. In this book she gives a process on how to go from eating to living on divine love and light. This is going beyond raw foodism. Can we live without eating? I think so.
In the Matrix? I don't think so! Environment must harmonize with and be conducive to diet and lifestyle. In the Himalayas, YES! United States (a major city), HELL NO! What she suggests is possible and can be achieved, but not here in the U.S. with the average person.
