What is "maraka"

Maraka ( Sanskrit: मारक) in Hindu astrology refers to the planet or planets that cause death at the end of a particular life-span, if the assessed life-span is not over they cause accident, ill-health, poverty and misery during the course of their dasha or antra-dasha or in the period of the planet associating/influenced by them. Each lagna has a fixed maraka or marakas. The two luminaries, the Sun and the Moon, and the lord of the 9th house generally do not become marakas. The lords of the 2nd and the 7th house, or the malefic planets occupying anyone of these named houses and associated with their lords are the Primary determinants of death. The Secondary determinants of death are the benefic planets in association with lords of 2nd and 7th house or the lords of the 3rd and 8th house, or the lord of the 3rd or the 8th associating with the lord of the 2nd or the 7th house. The Tertiary determinants of death are Saturn associating with any of the afore stated marakas, the lord of the 6th or the 8th associated with a maraka, and the least powerful planet in the horoscope. The transit influences of the Sun, Mars and Jupiter are taken into account for determining the time of death.
