In an individual birth chart, when the Sun is placed in Sagittarius and the Moon in Pisces, the themes of exploration and transcendence are blended. The core life energy of the Archer consists of the desire to widen their scope of the world through the deviation from the local and familiar environment. This departure can take place through the body, the mind OR both.
Sagittarius energy is futuristic and it’s a requirement that their exploratory and questing nature be exercised in order to discover pieces to the puzzle of life’s meaning. They need to constantly expose themselves to new and fresh environments to obtain the widest range of viewpoints possible about a given subject. The Centaur’s joy is in the leaving behind of anything which represents narrow or restrictive confines.
When the Pisces Moon uses the light of the Sagittarius Sun, it gives form to a personality whose reigning emotional need is to transcend the mundane and pedestrian and serve man and womankind in an extraordinary and unusual way. To sacrifice one’s ego in the name of a higher spiritual calling. This placement suggests a highly developed capacity for empathy and an ability to actually get “into the skin” of another individual. Hence, the requirement of solitude and times of “zoning out” to bring them into balance:
“These “escape” activities are necessary for Pisces since they have few psychological defenses and easily absorb the psychic influences of those they deal with. Especially those with a Pisces Moon have a persistent emotional need to escape from limitation and from the confinement of everyday life, the material world and the prison of their own mental patterns. At the deepest level, Pisces needs to escape from the limited “self”, from the ego-bound personal identity with all its fears and insecurities.”
You could say that this Sun-Moon combo is similar in that they both seek to rise above the everyday and commonplace. The Sagittarius Sun through adventure and the Pisces Moon through service. While Sagittarius is willing to sacrifice the comfort of relative “safety”, Pisces is nourished by relinquishing the trappings of the material world.
However, when these needs are overfunctioning, the Sagittarius quest becomes self-righteous and a wayward seeking of distracting activities which will satiate his or her animal nature, and the Pisces Moon seeks to either avoid reality completely, or create an alternative one which nurses their trepidations.
“However, one of the many contradictions of Pisces is that they often also seek to escape from self-knowledge! They frequently don’t want to know their true nature or others’ view of them. (a bit like the other two water signs- Cancer and Scorpio-they are most comfortable remaining in their private, subjective world, where they often hear what they want to hear or what they fear hearing rather than what someone else actually said). This is a key aspect of the Pisces Moon personality-that they often ignore or evade a realistic sense of self and a bluntly honest self-appraisal.”
At the very worst, this Sun-Moon combination can yield an individual who thinks they know it ALL, and wants to hear nothing to the contrary. A scholarly, erudite legend in their own mind, who also happens to be very sympathetic and humane.
Used constructively, there’s the potential to merge the higher mind of Sagittarius with the Pisces sensitivity and intuition to give birth to a master explorer and teacher of the metaphysical variety who greets humanity with compassion, acceptance and good will.
