Neptune retrograde represents the drawing of personal boundaries, and points to self-delusion, self-sacrifice and dependency. In the birth chart it indicates a personality with an inwardly directed spiritual idealism, in whose life intuition, the imagination, and dreams play an important part. This often represents the prodigy, or at the very least indicates some inherent talent manifesting at a very young age. The challenge of a retrograde Neptune is to maintain one's sense of reality and a daily balance in life, as a lack of practical focus has the potential to be the greatest limiter in achieving one's full potential.
