The Moon and Mars in the same sign, or in mutual aspect.
Fruit
Wealth made by one's own effort, and an acquisitive, driving temperament: the combination is read as a money-making yoga and as a hard one for the inner life, since the Moon's receptivity is joined to Mars' appetite.
Meaning
Chandra-Mangala joins the mind to the will, and the tradition reads the result as an enterprising person who makes money and feels the cost of it. It is the standard combination for a business life, and the standard warning about one.
