As Rick said, Max ... we are all listening to your very intense personal experiences in training.
Without getting too far off track, it sounds as though you are equating the study of Sanchin with pathwork done on the Tree of Life or Kaballah?
Basically, one travels up and down each path to learn lessons and find the key to open another door of learning and lessons. By paying attention to his/her body, a person is able to change/transform the body, mind and spirit. The body becomes more fluid, the mind is clearer and the spirit becomes more energized.
The person understands that at each stage there is more to learn or more truth to attain, but is unable to reach it because he/she has not fully learned the lessons of controlling his/her body and breath.
Each person has their own, as you say, blueprint, for learning. And to sum up, it is the repetition that helps us awaken from the forgetting circle to the memory one.
