Where does the logic come from? it comes from WITHIN!
And how does it get there?
The year Paul introduced PhotoReading. The Japanese had a device for flipping the pages of the books into your eyes. They determined that perhaps with the device you could probably install the 4 million books from the London Library into your head in 1 year.
Yet with the limited capacity of the conscious mind it would take 400 centuries (400 x 100 years) to understand it or access it. (that was in 1986)
Now they point out that the brain is processing some 2 trillian bits of information a second and yet consciously we might be aware of 2000 bits.
Your conscious mind tends to focus on what you think about most. Which is why the statement, whether you think you can or think you can't, you are right.
If you're having trouble with any aspect of the steps of the system and obtain some advise, don't,
try. Instead, just give it a go and see what happens.
