Do you feel that Khan Core is going to be helpful during lockdown? Or is it that you want to be ready for Stage 4 when the time arises?
Funny enough I had a similar concern about not doing Khan ST1 due to Khan Core (because my social custom will have Khan ST4); my current listening plan doesn’t use Khan ST1. I think doing the wide-scoping healing which can be done in near-isolation will make up for that.
