Sex is the Creative Principle

It is the dual desire force in Mind for expressing its One Idea. Without a division of the one unconditioned Light into two seemingly conditioned lights, Creation could not be.

Sex is not a thing, it is a condition of a thing.
An electrically balanced condition of anything is sexless whether it be a man, woman, electric battery, or the atmosphere.

A sexed condition is an unbalanced condition. An electric battery which is fully charged is dually unbalanced by the opposite electric pressures of compression and expansion. These two opposite unbalanced conditions violently desire to return to the oneness of balance from which they were divided into two. A short circuit between the two poles of the battery will give it that balance. We then say it is dead, for it will no longer perform work by expressing its desire for balance.
