Thanks for your post.

He would have PhotoRead the entire book and then Supre Reading & Dipping chapter by chapter.

Paul Scheele says, once you PhotoRead a book "it's in there"...meaning, that entire book has been absorbed by your inner mind. The next step is to "get active" with the material with the Activation techniques which turn on your inner mind to intuitively guide your conscious awareness to be attracted to Dip in to dozens of different places through the book.

If you have a highly detailed book, or textbook, you're best to begin activating by having a couple of (30) minute activation passes to get the structure of the whole book at a conscious level. Then, go back and fully activate each chapter one at a time. Treat each chapter as if it is a book in itself, and a Mind Map for each chapter.

Keep your Previewing time brief -- 1-2 minutes is sufficient.

Create and craft questions during Postviewing, as well as during your Activation passes.
