Dear Maura,
I think that it doesn't matter too much what mechanics you use. Different healers use different methods but have similar results.
I suspect that Master Lin tells us to push energy back into the spot 9 times, more to give us a structure to work with, so that we feel confident in doing the healing.
The main things are, as Master Lin says, Love,
Kindness and Forgiveness and then confidence in ourselves.
We are simply the channel for the healing energy.
Love & Light
