HI Karalee,
RI works on many levels. As Dennis Stephens said, it can not be run too much, but it can definitely be run too little.
RI takes up about 1/3 of session time for me. If I feel the least bit fuzzy during session I run RI. It makes things run smoothly and even brings up and presents material to be run.
RI also can work as an exteriorisation process. It is the heart of the TROM system.
For anyone having any difficulty running TROM, sufficient RI could very will resolve the problem.
Don’t take the flywheel analogy too literally. It only describes one of the many aspects of RI.
Regards,
