The Road to Oz appears to in the order of "Transformation from Within" which is the Black path of Causality and Love. That way changes a Paragnostic of the Red into a Paragnostic of the Blue. One who understands why something is true without yet being able to leverage truth in order to modify situations.

The Black path combines the paths of Transformation and Creation. 

The path of Transformation is along the Tetractys from 1 to 10.

The path of Creation is the specific absence of the path of Transformation and goes from 1 to 7 in the order of the days of the week and then goes from 8 to 10

The combined path starts at the center at 1 which is common to both and then alternates between the two paths till it gets to 8 which is common to both and then goes to 9 and 10

The path of Causality and Love

Stage 1 is called Self Awakening
       1  Clear - Sun - Sunday - Center
       Shaggy man shown the way not to go, where it all begins, everything that follows is in reaction to love. Ozma and Dorothy are BFFs (Best Friends Forever) and Ozma's love of Dorothy is why she is there in the first place - parallels - the path of causal love

Stage 2 is called Awareness of the Way Things Are
       2 Purple - Moon - Internal specific absence and Chaos
       Lost in a chaos of roads, display of the Love Magnet to Dorothy, who trusts the Shaggy man despite his appearance - parallels - perception that the self is not a thing but the specific absence of a thing. That what is perceived as the self is a specific absence caused by the interaction of the external and internal senses.

       2 Purple - Monday - External specific absence and Chaos
       They find Button Bright who is also lost, very very lost - parallels - ultimate lostness, when all the senses are inactive. Because self awareness is a specific absence created by the senses, no apparent self remains, only love, causality and recursion remain.

Stage 3 is called Underlying Mechanism
       3 Orange - Mercury - Internal categories
       Arrival at Foxville where they were going to be prisoners but became guests and were taken to King Dox - parallels - perception that categories and names do not define but are only descriptive. If too few, they are insufficient to cover all possibilities. If enough to cover all possibilities, they are too vague. Enough category to define a specific absence appears realer than the thing it represents.

       5 Red - Tuesday - External conflict
       The transformation of Button Bright's head because he was so dumbly clever. Perhaps the Shaggy man is not civilized. And I suppose the fowl that the foxes raise for food are not civilized either - parallels - too much involvement in the way things appear leads to losing oneself in them. Cleverness and all the other charactersistics of a person are externals like clothes. They appear to be functions of the self but are in reality relationships to the external world, the Extelligence, the Matrix.
