Neptune is an outer planet and is a transpersonal planet just like Uranus and Pluto. It is the ruler of the zodiac sign of Pisces and the natural ruler of the 12th house. It is a planet that is connected with unconditional love, and spirituality. Neptune is a planet of illusion, dreams and the fantasy world. It intensifies our compassion and sensitizes our intuition.
Reality gets marred with the interference of Neptune in our birth chart. Neptune is said to be the higher octave of the planet Venus and rules artistic pursuits and anything that opposes reality.
Neptune takes about 165 years to go once through the whole zodiac sign and hence spends around 14 years loitering in each sun sign. As it is a slow moving planet, people born within a timeframe of 14 years share the same Neptune sign. The aspects Neptune makes with the other planets in one’s birth chart and its transit positions hold much significance when compared to its actual placement in a natal chart. Your Neptune sign denotes the spiritual mission you are undertaking in this life.
