The PhotoReading step is taking in all the pages of the book like making a mental snapshot first.
PhotoReading is active reading where traditional reading as you were taught in your early years of school is passive reading.
Mind probing is asking yourself question. During PhotoReading you say a chant to keep the conscious mind busy. The non-conscious mind is always doing it's thing it stays busy anyway.
If you get the feeling you want more from the book and have no questions left, rapid read it. Then see if it was worth your time.
Learn image streaming if you want to learn to slow down the mind so the conscious mind can catch the thoughts.
Learn and apply the whole system. That works better than daydreaming about it.
