Prediction through Dasha System is the chief objective of Predictive Astrology. Maharshi Parashar has mentioned 43 types of Dashas in his "Brihat Parashar Hora Shastra". Here in this book the Vimshottari Dasha has been mentioned elaborately in particular, which is used extensively. Besides, the Ashtottari and Yogini Dashas have also been narrated briefly. Vimshottari Dasha system is based on constellation. This system is used throughout India and recognized by all. It is based on the lordship of planet. The native can have result according to the house of which the planet is the lord. So, it is essential to know the Karakatva of the house and the merit of the lord of it. The book has been composed keeping in view the problems of the students of All India Federation of Astrologers' Societies on the inspiration of Mr. Arun Kumar Bansal. This book explains the method of prediction on the basis of Dasha in any easy to understand manner. A learned astrologer has to make study of the three different parts of a horoscope - 1. Yoga, the combination of planets and Lords, 2. Period-sub-period i.e. dasha, 3. Gochar that is, transit. All the three parts are the supplements of each other. Yoga is most important among all the three parts. Period-sub-period i.e. dasha may prove to be futile if there is no Yoga in a horoscope. For example, Period-sub-period that of Lord of fifth house or of Karaka planet cannot bless a native with a child if there is no Santan Yoga in his horoscope. Likewise, Gochar too cannot do anything if there is no Yoga in a horoscope. So, all the three parts are essential to have the result.

This book deals with the determination of method of timing of events through dasha and transit. The horoscope and related divisional charts can simply give an indication about the auspicious and inauspicious probabilities on the basis of the study of house, house lord and significator whereas the timing of an event cannot be calculated without understanding the impact of major period & transit in operation so for getting timing of events in one's life, we use Dasha and transits. Dasha tells which planet is affecting the native at a particular time, whereas transit tells us which natal planet is vibrating because of the transiting planet. A combined result of Dasha and transit gives us the behavior of the native at a particular time. In nutshell the Horoscope and concerned divisional charts only indicate the promise in the horoscope, negative or positive, according to the position of house, house lord, significator, concerned house from the significator. But the time of fructification of event is indicated by the Dasha/Anterdasha of different planets. If a good dasha is in operation, the native will get good results according to the significations of the concerned dasha nath and its lordship in the horoscope. For determining the timing of events for various events such as education, profession, marriage, children, acquiring of vehicle, land and property, foreign travels, each subject is discussed in detail in different chapters. The principles to identify the timing of events are given with illustrations / examples.
