All the planets work in tandem and it does not happen that your life can be evaluated by the Dasa Lord only. Dasas have antardasas and each antardasa is further sub divided into 9 sub periods and each such sub period is again sub divided into 9 sub sub periods and so on details of which are given in my blog. So the life is dependent on the average potency of all 9 planets and you should not depend much on your horoscope as seen by wayside astrologers. Have a look at the Nature and Net effect of each planet in isolation.
