Don't "read" the words. Scan down the page, while attempting to notice an internal signal of some sort (sound, feeling, image). If you think you have received a signal, dip in and see if the text is related to your purpose. (sometimes, you have to go back a page or so to find the relevant piece).
There is an interesting parallel in "The New Psycho-Cybernetics." Dr. Maltz contends that the purpose of our conscious mind is to make decisions. Raw processing and problem solving are handled by the unconscious mind. He suggests that, once you have made a decision to do something, forget about it at the conscious level and let the part of your mind that excels at this work do its job. There is a tendency with activation to rely too much on our conscious mind to give us the results. Scan down the center of the page. Let your eyes feed the data to your inner mind while you focus your conscious mind on the search for "intuitive" signals. You've already fed the inner mind your requirements and your source by creating trigger words/probing questions and Photoreading the book. Maybe a crucial part of activation is getting out of the way and letting our inner mind do its job?
