Yeah they would. But personally, I haven’t re- listened to them and still have a strong connection to it. Don’t think that’s going to dissipate… that’s for life.
As for re-listening to the audios from the course… I think the first three are the most important in terms of energy cleansing and expansion. Body Primer, Energy Sensitivity and Healer Primer. Relistens of those will keep expanding your energy system. You can have a bit more liberty with how you listen to them and at what frequency as well. Just… be careful and don’t overdo it. You saw how people were getting overly exhausted their first run through. That could still happen as it would happen to me when I’d relisten sometimes.
