Query: Practical Support

The title of this book is, to be honest, a little silly. But after getting over Almaas' metaphor I found this to be one of the best spiritual practice books I have come across. Inquiry, when done properly, is an amazingly powerful practice. Almaas takes you step by step into a deeper understanding of how to do this practice. That said, this book is not for everyone. I would suggest that someone should have read Diamond Heart One and Two (for most people these are a better starting point than the Diamond Mind series) and also have at least a couple of years of sitting meditation experience before working with this book. Without that foundation, this work might only engage you at the psychological level. This is also a "workbook" with lots of inquiry exercises-take your time with it. I would suggest setting aside some time to work with it two or three times a week. The inquiries will take 15-20 minutes each and shouldn't be skipped if you want to engage this work fully.
