Astrological currents constitute inner-plane weather.

The ten outstanding types of inner-plane weather are the vibratory currents radiated by the ten planets, each with its own characteristic influence.

How individuals react to inner-plane weather.

"To understand individual reactions to the inner-plane weather mapped by astrological positions, it should be recognized that most of the actions of human life spring into existence, not as a result of premeditation, but due to habitual reaction to feeling, which in turn is powerfully influenced by the planetary energies which at any time are added to certain (i.e. planet-responsive) thought-cells of the unconscious mind.

The unconscious mind...is an organization of thought-elements into thought-cells and thought-structures.

This organization persists in the same astral substance that carries the vibrations of planetary influence.

Not only does a birth chart map the arrangement and volume of energy of different types possessed by these thought-cells, and therefore the individual's character, but the progressed aspects (i.e. temporary new energies) map the time when groups of these thought-cells acquire sufficient additional planetary power to attract (i.e. by means of psychokinesis - the power of thought energy to affect changes in substance and conditions) events of a (i.e. sympathetically resonating) corresponding nature."
