Of the Lagna, the Sun and the Moon, whichever is strongest will have its Dasa first. Then will come the Dasa of the planets in its Kendra and other positions. When several occupy together any one of these positions the precedence will be given to the planet which predominates in strength. When they happen to be of equal strength, that which gives a longer period, in years, of Ayurdaya will have its turn first. When there is equality even in regard to the number of years of the (Ayurdaya) of the planets, that which rises first after being eclipsed by the Sun gets its Dasa prior to its fellows.
