In vedic astrology the sign rising over the horizon at the time of your birth is called the Ascendant, Lagna or Rising Sign. The rising sign governs your personality, disposition and physical attributes, notably your appearance and general outlook. The sign and condition of the ascendant also affects your strength, vitality, health issues and the types of illnesses you may experience. Its influence is powerful, but may be modified by any planets rising and the condition of the ruling planet. The placement of the luminaries (Sun and Moon) and how they aspect the ascendant also affect the appearance.
