Itzhak Bentov was born in Czechoslovakia and moved to America, he became an inventor and specialized in the creation of new medical instrumentation.  He died shortly after writing this book in a flying accident.

None of which prepares the reader for the model of the universe which Bentov proposes.  This is a fascinating book and will be of interest to all who study psychic matters and are interesting in a “model” of reality which reflects their own experiences.
