Jupiter, the benevolent planet of expansion, wisdom and spirituality when placed in the 3rd house for the Libra ascendant brings about a mix of positive and negative qualities.
As per Vedic astrology, Jupiter is said to be in its mooltrikona state when placed in Sagittarius and Pisces. Since Sagittarius is the natural ruler of the 9th house, which is one of Jupiter's own houses and Pisces represents enlightenment, compassion and faith- two auspicious placements that evoke very different traits of Jupiter.
