It makes sense, then, that the most potent example of astrological synastry (harmony between two birth charts) involves contact between one person's Sun and the other person's Moon, or contact between the two Moons. Carl Jung, the renowned Swiss Psychologist, famously conducted a 'marriage experiment' in which he studied the birth charts of over 500 couples. What he found was an unmistakable trend of Sun-Moon contact between partners. To most astrologers, this came as no surprise-it has long been understood that when one person's Moon hits another person's chart in a significant way, there exists a strong possibility of lasting and meaningful romance.
When we learn these influences that the moon holds over us and astrological phenomena, we can use this information to our advantage. For example, during the new moon most people are not capable of rational thought. Knowing this can help you to avoid major decision making during the time of the full moon.
The New Moon. The New Moon is of more subtle nature. When this Moon touches the Sun she doesn't reflect any light. The New Moon is invisible to our eyes. The light of consciousness is gone for a short period of time and with it the self perception and self awareness. This moment signifies a clean slate, a new beginning into the next round of the Moon circling the Sun, the center of our universe representing the highest consciousness and life giving force for all the inhabitants of our earth.
