Thanks to andy and sniffle. i start to be confused with the word 'gel'. what does it mean? does it mean we acquire sufficient information from pass through the book serveral times or it means some additioonal details just begin to appear in our concious mind after serveral activation session.
Do we have additional knowledge other than which we acquire by superread and dip?
thanks to sniffle for telling me that familiarity can be acquired 
when it happen is it like reading a book for 2nd time?
