Jupiter, the planet of expansion, wisdom and spirituality is considered as one of the most auspicious planets in Vedic astrology. When placed in the 12th House in exalted state for Leo ascendant, it can bring about significant changes and opportunities in one's life.
As Jupiter is the lord of the 5th and 8th houses, it indicates creativity, intelligence, occult sciences and sudden gains.
