In his books Robert says to stop stimulating the primary energy centers when you get any kind of a response. I get a small response almost immediately, some just a minute or two more so I move on to the next one but when I see 10 minutes alloted for each or read about people who are doing it a lot more I'm wondering if I am giving enough time to these centers even though the directions are clearly to move on. So for many weeks now it is just a few seconds for each center. What do you get from doing more after the initial response? Some discussion please?
