We have significant reservations about this book because of the questionable business practices of the author Sean Shayan. While his marketing suggests that his projects and the Temple of Ecstasy are spiritual, caring, community organizations...their past practices have appeared to be purely profit driven and set up to take advantage of the uninformed. As an example, throughout this book Shayan mentions a single retail source for Salvia divinorum extracts which he fails to mention is his own company. The book is quite small with large font and doesn't include any novel information that we can find. We decided to include it in our library in order to be inclusive of the available literature, but we cannot recommend it despite the lack of published resources on the topic.
