the process is chaotic and deterministic

this can be, but does not have to be and I am talking of over twenty years of experience working with clients and helping them to change their map of reality, in way that is more fulfilling and open, then their previous one. Sometimes it can be very easy and fast and at times it can be slow and take some effort. But it is always amazing and gratifying what can happen to someone when they are able to shift their map of reality.
