What is Sun: Sun is the supreme self which is presents in all of us. Sun is the shiva the unchanged and supreme power. We all can merge in this supreme power through yoga and meditation practice. However through the astrological point Sun Sign is the astrological point in birth chart at the time you born. It is fiery planet and rule sign of Leo. Depending on the the Sun Sign and position of house is sited it define your self esteem, ego, pride and your health vitality. Whenever sun conjunct with other planets it illuminate the quality of that planet. So what happen when Sun conjunct with other planets.
What is Moon: The Moon is watery planet, as it rules the sign of Cancer. Moon is the emotions, feelings and is the part of you that reflects the way you feel. Moon also represents mother, imagination, emotional body, it shows the way you think and react to situation. How emotional or unemotional you are depends upon the condition of the Moon. Your Moon is your comfort zone or uncomfortable zone depending on the Moon Sign and house placement. Moon is receptivity and subconscious mind which act on past life karma.
Sun and Moon conjunction:
When the Sun and Moon are in conjunction, it means the person born black Moon (Amasaya) if the conjunction is exact. When any planet comes closer to Sun its means it gets combust in the rays of Sun. This is like conscious mind (Sun) comes together with unconscious mind (Moon). We all have different areas in our life and they are needed as they are. Moon is the planets of inner peace and what happened if our inner peace get burned up. I think we will not feel good. This is not the good conjunction to have because it is like as fire and water coming together and what happened when this thing happen? This conjunction can shows no peace of mind or agitated mind. Depending on the sign it can be less or more detrimental. E.g. if you have this conjunction in Aries then you can be enthusiast, with a natural feel for new beginnings, and you know how to use your new ideas, but if you this conjunction in Scorpio where Moon gets debilitated then what happened? Maybe you may feel more unrest. There are many possibilities depending on your personal chart. This is just general meaning and there is no need to take seriously. Everything have negative as well as positive effect. Positive benefit of this conjunction is that these people are good in meditation because in meditation we try to connect mind with our soul together. They have good instinct of inner feelings and very clear what they want from their life.
Remedy: My suggestion for these people that they need to drink lot of water and try to manage their emotions in control. They should not react spontaneously and they should think thoroughly before any emotional reaction. They should respect their mother it does not matter whether they are happy or not with their mother. Those people who have Moon not in good condition, its means they have done something wrong with their mother and now in this birth they need to fix their karma with their mother and if they not, they will suffer mentally.
