In a nutshell
Raoji has repeatedly demonstrated use of dasa systems effectively with a sound methodology and common sense.If current period is bad and ones to come in the future do not show a rosy picture then this can determine the trend.This level of details are overlooked by astrologers. I have several books of Raoji and I am amazed by the depth of research but It would be appreciated if someone could write a book or anyone could write an article or book that demonstrates judging 1-12 house using a single horoscope from parasara and jaimini's angle using both classical principle and modern approach using navamsha ,divisional charts and timing events using popular dasas like vimshottari,ashtottari,yogini,chara,sthira,kalachakra
dasa along with transits and ashtakavarga .Strength of planets also taken into consideration. This will demonstrate level of details required to predict one horoscope to give it a very high success rate.this will be like a summary.
