Best source of information.
The best source of thought, insignt and application is probably the classic by Dane Rudyar -- the Lunation Cycle. He postulates that the division of the Moons full cycle into 8 parts, each 45 degrees, enables you to interprete the Moon relative to the Sun based on which phase it is in. The phases, starting with the 0 to 45 degree zone are given the following "names": Performer, Worker, Activist, Analyst, Seeker, Believer, Changer, Prophet. Other authors have extended this idea to planetary pairs such as Saturn-Moon, Jupiter-Mercury, Mars-Venus, Saturn-Jupiter, and Uranus-Saturn. Of course you can apply this idea to any pair, you just have to adjust the phase meaning to suite the core pair meanings. Dave.
