The 8th house from the lagna, or the ascendant, is associated with longevity and death in Vedic astrology. The strength of the 8th house and the lord of the 8th house are important indicators in determining which planet can bring a long life. Generally, Jupiter, Venus, and Mercury are beneficial for long life. For these planets to effectively grant a long life, the 8th lord should be strong by being in its own sign, exalted, or in a kendra house. Additionally, it should not be afflicted or associated with benefic planets.
