You want to give yourself to something completely. You also want to keep your feet on the ground. Both keep losing.
What it looks like in a life
Jupiter opposes Neptune about six years after each of their conjunctions, so everyone born in that window carries it; the house axis and the contacts to your personal planets make it yours. You swing between the ideal and the accounting. You commit with your whole chest and months later you are the doubter in the room about that same thing. You attract people who need saving, or you become the one being saved, and the roles trade places more often than either of you admits. Belief and doubt are both loud in you. You have left a faith, a scene, or a relationship because it disappointed a picture you never described to anyone.
The gift
You see the ideal and the reality in one look, when you are not swinging between them. That makes you unusually good at telling someone the truth without taking their hope away. Your faith has been argued with, which is what makes it durable. You can work with who a person is while still seeing what they could become.
The friction
The seesaw and the projection. You put the vision on somebody else and then blame them when it fails, or you take on their mess as your calling and lose the outline of your own life. Disillusionment shows up on schedule, and each time you treat it as an event rather than a pattern with your name on it.
The esoteric layer
Neptune was found in 1846, so the ancient sources say nothing about it. Jupiter alone holds the old title of greater benefic. What follows is Bailey and modern. Two is polarity, and esoteric astrology reads the opposition on full-Moon logic: illumination through the other, the pair held in tension until a third reconciling point appears. Bailey's esoteric astrology calls Neptune sacred, on the ray of devotion, and names glamour as its danger. The reconciliation here is a faith that went through the disappointment and did not need the fantasy afterward.
Where this goes
The two houses name where you idealize and where you actually live. A full natal reading finds the third point between them, which is where the swinging stops being the whole story.
