In Vedic Astrology, Moon is what signifies the human . Moon is the heavenly body closest to Earth, the cosmic and magnetic influences and energy of all other planets reaches Earth through the Moon.
Another key thing to note here is that mind is ruled by Moon and all influences on the human being whether physical, psychological or supernatural affect the human mind since they are filtered through your Moon Sign. The human body which is ruled by SUN may or may not respond to the mental / psychological / supernatural influences.
This is the reason why Vedic Astrology reckons the planetary movements based on your Moon Sign.
