In the first chapter, Rao gives some hints: The condition of the dasha lords must be examined in the birth chart, and the navamsha. If the question is about career, then you must additionally use the dashamsha chart, if about siblings, the drekkana, if about property, the chaturthamsha, if children, the saptamsha, if parent, the dwadashamsha. Do a combined reading: Give 3.5 points for the condition of the natal dasha lords, 3 points for the navamsha, and half a point for the third (divisional) chart.
Every event must be examined through these three charts. In Vimshottari dasha, examine the major period, the sub-period & the sub-sub period, checking for the mutual positions of the major & sub dasa lords. If they are in kendras or trikonas, it's favorable. In houses 2 / 12, or 6 / 8, there are difficulties. Consider the ownership of the dasha lords. Look also at the Yogini dasha in effect. Triple check with Chara dasha. Re-examine from the standpoint of the moon. Finally, look at transits, never forgetting the sarvashtaka. Rao expands on this in the rest of the book.
About the Author:
From relative obscurity in 1990, K.N. Rao has become one of the leading Jyotish astrologers. He is the retired Director General of the Indian office of the Comptroller and Auditor General, with a life-long interest in astrology, which he learned from his mother. He calls astrology the super-science of the new age. He directs The Astrology School at the Bharatiya Vidya Bhavan, New Delhi.
He is a prolific writer. He believes deeply in research that brings solid results. He is unafraid of redefining ancient Vedic scriptures for modern times. He eagerly seeks out obscure techniques, and, once he has tested them to his satisfaction, adds them to his ever-growing rapture. He is challenging & surprising. He is also cranky & apt to tell a fool what he really thinks of him (and in print, to boot), a fault which I think we should forgive.
