The way I understood it was that it’s a 72 hr break between listening to the 3rd Body Primer and the 1st Energy Sensitivity audio.
For example:
Let’s say you start listening to Body Primer on a Monday.
Monday: Body Primer
Tuesday: Body Primer
Wednesday: Body Primer
Thursday: Break
Friday: Break
Saturday: Energy Sensitivity
and so on…
Then it would be 72 hr after listening to the 3rd Body Primer that one listens to the 1st Energy Sensitivity.
Hopefully sammyg can confirm with us which is correct.
