This reminds me a bit of Alejandro Jodorowsky's approach to psychotherapy[1], in which trauma and neurosis are resolved by performing an act related to them. For example, if conflict was left unresolved with someone who has passed away, he instructs talking over the problem at the grave, and then painting "peace" with honey over the tombstone. Most of his suggestions are quite outlandish I recall his cure for agoraphobia was having your friends carry you inside a sleeping bag to a plaza where they would simulate your "birth into the world".
