Pay attention to the simple motion of the MOON through the signs.  If we are paying attention we are able to anticipate the underlying Mood of our days.
As we watch, the Moon (along with the general mood) drifts through one sign after another, creating observable patterns.
Every 2.5 days the Moon shifts into another sign.
The order of the Signs is as follows:
Aries, Taurus, Gemini, Cancer, Leo, Virgo, Libra, Scorpio, Sagittarius, Capricorn, Aquarius, and Pisces.
The Elements tell us a great deal about how the Signs encounter each other and work together. In considering the compatibility of the Elements think about the fact that Air feeds Fire, Fire thrives on Air; Earth Supports Water, Water shapes Earth. Compatibility is almost as simple as that!
Each Sign belongs to one of the Four Elements:

  • Fire Signs:  Aries, Leo, Sagittarius – Fire Signs are warm, enthusiastic, and impatient
  •  Earth Signs:  Taurus, Virgo, Capricorn – Earth Signs are dependable, conservative, and purposeful
  • Air Signs:  Gemini, Libra, Aquarius – Air Signs are curious, objective, and social.
  • Water Signs:  Cancer, Scorpio, Pisces – Water Signs are private, self-contained, and sensitive.

Each Sign also belongs to a Modality: 

  • Cardinal: Aries, Cancer, Libra, Capricorn – Cardinal Signs are active, forceful, and assertive
  • Fixed: Taurus, Leo, Scorpio, Aquarius – Fixed Signs are cautious, stubborn, and not readily altered
  • Mutable: Gemini, Virgo, Sagittarius, Pisces – Mutable Signs are adaptable, easy-going, and flexible

If you deeply understand the Elements and the Modalities you are a long ways toward understanding the Signs. Each Sign belongs to one Element and one Modality. It is a neat, tidy system. See if you can understand how it works.
Meditate on the Elements and Modalities, bring them together into the Signs. Can you feel how deep that understanding can take you?
