Saturn.

That which constricts. The solid principle, through deciding completely and surely what an object is, solidity is found. Therefore there are no variables in which make it gaseous or amorphic. The planet of hard lessons and karma. That force of energy which causes an entity to become something, to essentially doubt that answers may be found without. Symbolizes what an entity thinks the outer matrix desires of it. Also what the outer matrix desires of it. That which an entity must do to survive. The contraction of all possibilities in order to meet a single goal.
