The Moon in astrological psychology represents the sense of self we gain through our feelings and emotions. The Moon signifies our child-like responses, which can be spontaneous and fun-loving, and it also acts like a mirror, reflecting what's going on around us because it can sense and pick up on atmospheres and feelings very easily. It's a sensing tool, the part of us that feels.
Of course, the way the Moon operates and expresses itself out in the world will be coloured by the Zodiac Sign it's in, which acts like a "costume" which clothes the Moon and modifies its expression. On a basic bottom line level, its expression is influenced by the Element (Fire, Earth, Air or Water) of that Sign.
Fire Sign Moons - those in Aries, Leo and Sagittarius - will tend towards optimism and enthusiasm. Fiery Moons want to be noticed! They will be lively, expressive and outspoken with energetic feelings that demand attention.
Earth Sign Moons - those in Taurus, Virgo and Capricorn - will have a strong practical streak. They may be a bit fussy, but they are down-to-earth and generally enjoy sensual things, espcially Taurus Moons! They will appreciate good quality in all areas of life.
Air Sign Moons - those in Gemini, Libra and Aquarius - love to communicate and share ideas with others, so they enjoy seeing friends and family, chatting and catching up on news, attending talks, lectures and events which will stimulate the mind.
Water Sign Moons - those in Cancer, Scorpio and Pisces - tend to be very emotionally sensitive and tuned in to the feelings of others. They can be very caring, needing to express their feelings and regard for others in tangible ways. But they can also be moody, living life through their feeling nature.
The Moon, representing the sense of self we get through our feelings, is often a part of the personality which is neglected or repressed. We may have been brought up not to show our feelings; they might have been regarded as unacceptable or not something to share or talk about in the environment we grew up in. But they are there all the same, and sometimes they need our attention.
In this video I talk about some of the ways we can work on developing and understanding the Moon and our feeling nature. There is more on this in my book The Living Birth Chart. Click on the Books by Joyce Hopewell tab at the top of the page to find out more.
