According to classical Vedic astrology and the BPHS tradition, Jupiter signifies wisdom, knowledge, dharma, teaching, expansion, and blessings. It is known as the Guru, representing guidance, higher learning, spirituality, wealth, and children. A strong Jupiter can give wisdom, optimism, prosperity, ethical conduct, and spiritual growth, while an afflicted Jupiter may create poor judgment, overconfidence, lack of direction, or moral confusion. Jupiter is essential for understanding growth, faith, knowledge, and life direction in a birth chart.
