When malefic planets occupy the 6 bhavas counted backward from the 12th, the whole, a half, a third, a fourth, a fifth, or a sixth, respectively of their Ayurdaya is lost. When benefic planets occupy such positions, the loss is half of that incurred in the case of malefic ones. When several planets are in a bhava, only the strongest of them causes a reduction in the Ayurdaya. Satyacharya says so.
