Astrologers usually do a few steps before analyzing a natal chart, and finding out the exact rising sign, Sun sign and Moon sign is one of the important steps. Rising sign and Sun sign are obvious and easily understood - rising sign is the first house of the whole chart, it shows someone's appearance and body composition; and Sun sign is our first step in understanding astrology. So comparing to Moon sign, it is more difficult to understand, not only because it is related to our birth time, which not everybody knows; but also it is our sub-conscious mind. So not many people pay much attention to it.
Then why is Moon sign so important? Physically, Moon is the closest planet to earth, it has effect on our sea level and it affect our mood and body, e.g. women's menstrual cycle. And in astrology, Moon represents a lot of things, which are all very closely related to us - mother, food, sub-conscious, basic needs, etc. It seems difficult when I talk about sub-conscious, put it in another way, it is our personal feeling, e.g. you feel familiar with someone you first met; you think of a particular food when you are hungry, etc. And to be more direct, Moon is our emotions.
You may think that we are adults and maybe in a certain professional field, we cannot act like children, yelling and shouting and crying when we fill upset, and that's life. True... but emotional health does affect our physical health, such as depression, lack of appetite, or even cancer can be caused by emotional issues. That's why in my own opinion, the key to look after yourself and make yourself happy, is to make use of your Moon sign energy. (Due to limited space, I will use the 4 elements to analyze.)
Water Element: Cancer, Scorpio and Pisces
If your Moon sign is in water, you can cry easily, maybe just because of a love story, or found a news saying that someone mistreated a kitten. So, just cry when you are upset, or talk to your close friends, getting comfort is a healing process.
Earth Element: Taurus, Virgo and Capricorn
Moon in earth, you can be a foodie! As earth signs are very practical, what's more practical then consuming food and absorb it into your system? (that's so true...) These people may also like to tidy up stuff and throw away unused or unnecessary things, as this process can settle down their mind.
Wind Element: Gemini, Libra and Aquarius
Wind represents thoughts and thinking, they are logical, so they are less likely to have mental issues, but they do have down times, but the key is to speak, talk to someone. The difference between wind and water is that wind just want to spill things out, doesn't matter if there is any feedback; however, it is very important for water signs to get comfort and understanding during the communicating process. So there is some difference.
Fire Element: Aires, Leo and Sagittarius
It is not easy for fire Moon signs to be upset, this is quite similar to winds, but fire Moons are more hyper, they don't have time for depression or upset! But if it does happen, they just need some exercise, move their body. The most upsetting thing to them must be lack of progress, so in the exercising process, they can stop their thoughts, and they can resume to their hyper mode afterwards.
The above is only a simple analysis, but as aspects of the moon can affect its energy, it would be much better if the natal chart is analyzed as a whole. Next round I will share how to use Moon to plan for your month.
