A normal-sized mount of this kind will supposedly be indicative of a sensitive, romantic and imaginative type. If flat, the contrary is indicated, that is, unimaginative, possibly unstable and even bigoted character. Where it is large, then we can interpret that as being a person who is over-imaginative and introspective.
Directly above the mount of the Moon is the upper mount of Mars. It would seem that it's best to have a normal-sized one of these, because if this is the case, you are meant to be morally courageous. It it's flat, then you're cowardly, and if it's large you're bad tempered and cruel.
We'll contrast this with the lower mount of Mars on the far side of the hand, above the mount of Venus, I spoke about first of all.
With this mount, if it's normal size, you're meant to be physical brave and not a panicky sort of person, you're violent and argumentative if it's large, and cowardly if it's flat.
adj. 反省的,内省的
