i tried to learn harry's memory systems before;i,e. without the PRing..but i found it was a little tricky,not hard.
but after i learnt PRing i thought that if i were to learn harry's memory sytems as well along with Pring ,then it would make a powerful fusion..so i Phtoread harry lorayne's book,the next day i started activating it, using SR and dip..i immediately found out that it was easier to understand,and listening to harry's train of thought,to zero in on his point of view..and i also got many inner signals guiding me to do certain things to make it more effective...Photoreading and Harry's memory sytems would indeed make a powerful Duo.
