I guess it depends but usually I take a break after about 6 books just for the sake of taking a break and do the books over 4 days just for convienience sake. You see Direct Learning to me is just letting my mind know what I want it to do. I can get results from 5 book complete in itself. By doing it over 4 days I am only really solitifying my personal intention and giving my mind more options as to how it can take up on the learning.
The Personal Genius paraliminal is to help you get into the flow state. The ideal state for learning, working, thinking.
The paraliminal with the Genius Code course is to help you intergrate and use the techniques from the Genius Code course. It is excellent for getting deeper into the image stream experience and going for answers.
