Natives having Moon, Mars and Jupiter together in a horoscope are physically attractive. They tend to be popular among the opposite sex. In most houses, this placement brings wealth and power to the native.
Such a person however has strong aggressive instincts and is short-tempered and reckless. There is a possibility that the native may have marks of some wound. If this conjunction is under affliction, the native can become adulterous. Such a native may have illicit relations, vices, bad habits such as theft, and addictions, especially to women.
