Jupiter has now firmly entered Sidereal Pisces, the feminine sign ruled by Jupiter. In Vedic astrology, the traditional rulers are used, so Neptune is not the ruler, Jupiter is.
Pisces reveals the mystical nature of Jupiter - the internal, reflective nature. Through Pisces Jupiter reflects and internalizes his energy. Showing an inner, emotinal and creative expansiveness.
From May 2010 - May 2011 Jupiter will be in Pisces most of the time.
This will bring a high potential for spiritual breakthrough and meeting important teachers for the next year. Especially those who have important planets in Sidereal Pisces (most likely Tropical Aries) will feel this.
The nature of Jupiter is to connect us with big things through which we expand and grow beyond just feeling happy and contented on Earth. Jupiter gives a sense of meaning to our life and also many of the things we are so looking for like money, children, fame and notoriety. Yet Jupiter also brings the disappointment that accompanies our rise and fulfillment in life.
