Together 10 Recursion, 9 Causality and 8 Identity are entire negativity and thus are the specific absence of, and thus evoke, Positivity which is the fourth aspect of Recursion. It is named Positivity and Relationship.

Positivity is 1, U, Clear. It is in the centermost circle, the middle one in the third row. Its planet is the Sun, its metal is Gold and the color is Clear as the tarnish of Gold doesn't exist.

The characteristics of Underlying Recursion as the single axiom are reflected in these first four aspects of Underlying Recursion

Necessary        Recursion

Generative       Causality Love

Self-defining    Structure Identity

Unique            Relationship Positivity

Rather than defining the rest of the planets singly and then going through the four paths planet by planet, meaning by meaning, I will start here with the first path, the path of Transformation, Evolution.

1, the Sun, is Relationship per se. It is the Ideal and the basis of Number.

Instead of defining a geometry based on boundaries as in Euclid, Blavatsky defined a geometry based on arbitrary points in indeterminate space.
One point doesn't define much. Two points defines quite a bit. etc, etc. Parallelism is defined by four points rather than that being a postulate.
The geometry based on points is an amazing construct but as it doesn't seem to appear in Baum I won't get into it.

As Relationship relates to Relationship, the Relationship of Relationship is...
