Stick to the process and if the session deviates, manage the client's communication then get back to the session.
The facilitator should not be wandering off the course of the session, asking questions or disturbing the client's flow. The purpose of the facilitator here is to just ask the question or provide an instruction, gently but firmly.
You keep the steps of the process separate.
A positive result would be when the client is experiencing some or complete relief from their issue, with a noticeable improvement in physical and emotional well being. Never leave a process until the original condition is in a better state than it was at the beginning. Always let the client finish the step they are on, before moving on to the next step.
Once the original condition vanishes, then begin again with a new focus or stop the session.
