This is an interesting area for discussion.
Photoreading or Mental Photography is a basic part of our equipment. It isn't anything new, though it may be new to the general public. These are techniques that have been practiced probably for thousands of years by more esoteric monsastic scholars in their work of safeguarding the knowledge of humanity.
You may like to investigate one story of this technique as it was told in the somewhat controversial book "The Third Eye" by T. Lobsang Rampa. In any case this book predates anything Paul or that other company did with the techniques.
In it we see how the monks learning the system of Tibetan medicine would use these techniques in their study. They would enter the appropriate meditative state, diffuse their vision with a soft gaze and blaze through the texts.
In any case, if you ever meet Paul and Pete at one of their events, which they guarantee, you will get to know their integrity and sincerity, which is profound, as I now do.
