The sun is our vitality. The moon is our sensitivity. The planets orbit at various rates and harmonize like the parts of an atom, like a musical chord in three octaves. The inner set is close and quick: expressive Mars, receptive Venus and electric Mercury. The outer set is slow and heavy: deep expressive Pluto, deep receptive Neptune and deep electric Uranus. In the middle, Jupiter is expansive and Saturn is centering. Our planet, Terra, is at the balance point, holding a water atmosphere and growing life within it. [Exerpt from the astrology primer.]
