The various cosmic energies that, although not concretely manifest, can be perceived on Earth. The word comes from the Greek 'energeia', or activity. Astrologers often talk of energies in connection with astrology. For example, the American astrologer Stephen Arroyo describes astrology as the language of energy.
According to this idea, the three qualities cardinal, fixed and mutable express different patterns of energy.
- The energy of the cardinal signs Aries, Cancer, Libra and Capricorn is centrifugal in nature.
- The energy of the fixed signs Taurus, Leo, Scorpio, and Aquarius is centripetal.
- The mutable signs of Gemini, Virgo,Sagittarius and Pisces have an energy which is spiral-like.
Arroyo calls the planets energy regulators and writes "the planets characterise the way energy is exchanged between individuals and the potential inherent in the universe."
