This is just my random thought of the day.
John Michael Greer once said the path to success isn't learning a lot of rituals, it is about learning a few and doing them very very well. In short, he was arguing for specialization.
While boring, I wonder what the effect would be of calling up each spirit on the tree, asking him, her and/or it, to purify that part of myself. When one gets to the top, start over over again.
I don't think I have the discipline to do this. It is just a thought.
