Jupiter is the most auspicious and beneficent planet. Wealthy and influential individuals generally possess a strong Jupiter in their horoscopes, and this reflects the rich rewards of positive karma accumulated in previous lives. Jupiter governs religious activity, financial affairs, personal happiness, and teaching. Jupiter also determines one's spiritual orientation. It is associated with the color yellow, the bodily fluids, education, pilgrimage places, and transcendental wisdom. The Sanskrit name for Jupiter is "guru," indicating a source of divine knowledge and spiritual insight.

If Jupiter is exalted one will be a leader of men, powerful, respected, although susceptible to anger. But if the position of Jupiter in a person's horoscope is debilitated Jupiter can cause personal unhappiness, egotism, sloth, and legal problems.

Gemstones Jupiter's energy is transmitted by natural yellow sapphires, topaz, citrine, heliodor, and other flawless (eye-clean) yellow gems.
