Doesn’t this say “practice make perfect”? And I read (but can’t remember the book nor the author) that a technique for memorization is to use association (thing-to-remember with something [picture; song; movement/movie/dance;…] – object-already-know).
I have doubts about the gesture for memorizing scripture by bending the upper part of the body forwards and backwards while reading the words (as used in Tibetan monks training). I think I would remember backaches more by doing that ;-)
