Moon, as a planet in the horoscope, plays the most important in the most difficult times. Suppose someone has temporary job loss, business loss, a relationship issue, or diseases, and your Moon (mind, temperament, and inner strength) is not good. In that case, you are likely to feel directionless/add to your miseries. One can handle the worst situations if your mind, your thought process, and your inner instincts are in your control. But if you have a weak Moon, you tend to depend on what others say, and your decisions and actions are likely to be influenced by others than using your own wisdom. This can be your relationship with females, eating habits, sleeping habits, clothes you wear, and many similar personal decisions. Now that is the biggest issue with a poor moon position in your chart. If Sun bestows power and authority, Moon governs your mind and thought process to best use this power and authority. Moon represents what you are intrinsically – means yourself in the true sense.
