Regeneration is about 11 months old, so I’ve only done 3 such retreats.
In those cases, I didn’t stack, but that is only because I was not working on an issue brought up by any other sub.
So yeah, if I wanted the retreat to be focused on say my sexual past, I am totally open to stacking Reg with PS.
I can write a longer reply if you want:
How Simon uses Subs for Healing - The Speculator’s Guide.
But to you personally @Malkuth, I’d like to say that:
If your queries about Regeneration have awoken from Emperor v4’s New Beginnings, then DON’T change your stack. Journal for couple more weeks.
NB has a different, more powerful mechanism for healing, and I feel like another healer will actually slow it down, instead of helping.
I’ll write more about NB on the Early Impressions thread today.
