Personally, I believe the answer to that question is yes. Astrology means you believe in everything about the planets; their movement, and behavior comes with it. Therefore, you believe that they can influence your mood. Astrologists believe when doing a prediction, the first things to prepare is a birth chart. The birth chart is the blueprint of your past, present and future life. It shows the position of planets both in the benefic and malefic state in various houses, the favorable and unfavorable period and possible future events.
There are nine planets in astrology; the Sun, Mercury, Venus, Mars, Jupiter, Saturn, the Moon, as well as the shadowy planets Rahu & Ketu. Each planet has a particular behavior and has a story behind it. The 12 signs in astrology are governed by these planets and, to some extent, carry the similar traits. They elaborate on the astrological study by studying the emotions that we all experience. They base the findings on dividing the form into12 houses. The nine planets travel around the sun and moon in these 12 houses and the 12 zodiac signs simultaneously. The movement and its compatibility with each sign create the prediction. To put it in a nutshell, astrology studies the movement and behavior of planets and their effect on humans with the help of calculations and observations. You might be surprised to learn that astrology can influence your mood swings and decision making. The planets grant good mood, sensible decision making, good luck, success, happiness and more! People close to you might, at times, not be able to absorb this change or have sudden emotional mood swings, which are the result of the planetary imbalance in life. For example, if a planet is in the malefic state in your house of love, then you are likely to face problems in your love life.
Astronomy is about understanding the universe and its contents based on physical law, or rather a set of rules which are hopefully self-consistent. The “experts” say that, just as the Moon causes ocean tides on Earth, so does the gravitational influence of other planets effect your mood. The so-called tidal force on a spherical body, such as Earth, from another body, such as the moon, originates from a differential force. This is a bunch of science lingo for the force being stronger on one side of the Earth than the other. This induces a distortion of the sphere’s shape, which causes stress on the body (Earth). This theory applied to your body and the planet’s movements can explain the effects the movements of each planet make. You may feel happy for a few and then sadness, depression and deprived and later become angry due to this effect. When it comes down to it, astrology is about belief. If you believe strongly enough in something, that thing can manifest. So, if you think the planets are affecting you, then they are. This grants you control over shifting these emotions to the opposite direction. No matter what, it is important to pay attention to shifts in mood. Once you take notice, it gives you the control back over them.
