Lots of practitioners in many modalities opt for an hour of treatment. Chiropractors have a very short treatment time followed closely by medical doctors. Therapists run a 45 to 50 minute hour. Reiki, massage, reflexologists bill by the hour. Perhaps life coaches do as well. And, yet … I do believe amazing results can be made in much shorter sessions.
This is a theoretical, non-scientific idea I have about how to proceed with energy sessions. It will all go better when the practitioner and client show up to work or play together.
