I have only recently been introduced to the concept of chaos magic. I have obtained one very important verification from my exposure to the concept. (as I understand it)
If a person can make literally any process a strong enough focus for mind to transform the existing mental/physical reality into something more pleasing... then it's not the process at all, it's focus and clarity of mind and desire. (I know, eons old 'news-flash')
Following that train of thought, no process/system at all would be required for a person to express their full potential if they had sufficient focus and a pure desire.
Of course, a good process/system can be really helpful for getting a person to that state. ;-)
