Hi Susan
My understanding is that for head related issues you clear the four energy points in the head of blockages, one after the other starting with C7 and then give energy back to each of them, when they are all cleared. For problems arising in other places you would clear C7 and put energy back in before moving on to other parts of the spine which might need clearing.
I always give energy 9 times to the Lower Dantien before doing the Small Universe, whatever the problem area I'm working on. Let's also see if this is confirmed by other people on the forum but this is what I do.
Love
Kev
