The Amsayu method is one of the classical techniques in Vedic astrology used to estimate a person's lifespan. It is applied when the Ascendant (Lagna) is stronger than the Sun and Moon, and relies on the Navamsa divisions of planetary longitudes. Unlike Pindayu or Lagnayu, Amsayu emphasizes mathematical precision and planetary dignity, offering a karmic snapshot of vitality and longevity.
This method is especially useful for astrologers seeking a quantitative Ayurdaya estimate, and it integrates Bharan Sanskar (enhancement) and Haran Sanskar (reduction) based on planetary strength, exaltation, retrogression, and debilitation.
