Actually what I was getting at was that even though the Schumann is changing the other frequencies are still relative because in a sense they have morphed too even though this is not measurable.
I think the frequency sets used for healing are still viable because everything is shifting in a relative manner.
For me the reason that we can (choice) leave behind things (on the outer stage)that help resonate us back into order is because there are purer, quicker ways to do it using our intent. This of course requires inner clarity for maximum effect.
