Dr Shankar Adawal, the author is a management professional. He has over the last thirty years worked with various prestigious corporate in India and abroad. His experience of working with L&T Xerox, Tata, Nortel and with a leading energy major of the country, alongwith a jyotishcharya from Varanasi gives him the perfect blend of intellect and logic.

His passion has been astrology, a passion that fell his way in childhood, a zeal that he picked from his father. As a child he often saw his father, a bureaucrat and an astrologer, getting admiration from many eminent astrologers, which inspired him. He used to spend long hours participating in intellectual debates that his father used to have with his friends and fellow astrologers. With thousands of books in his library, free consultations through magazines, television, portals and newspapers around the globe, he continues his journey on his passion. He has been felicitated and awarded for his contribution in this field. He also has keen interest in Human Rights.

The notion that astrologers can unfold lives and reveal what waits at the next bend is a thought that comes to all and populist claims have inspired the author to come up with a series of books that will discuss the various aspects in astrology, putting together the research and findings by various groups and the experience gained during his journey. The purpose of the encyclopedia is an attempt to put a clear understanding of the process of astrology, taking into account the first basic principles and dealing with different topics. The encyclopedia which would consist of over eighteen books, is intended to be brought out over a period of two years. These would cover the basics in astrology and then go on to the predictive techniques, the nadi astrology, tajik, yogas, nakshatras, rectifications of birth time, vargas, dashas, mundane prashna , muhurta, remedy and other aspects of interest. The advantage of this would be that both students and those who want to pursue research can progress the understanding of this science in a systematic manner. Also the complete set will be of great value of those in India and abroad who want to understand various levels and will give them the flexibility of dwelling into the complexities in a coherent manner. With the growing interest to learn this science in various countries, the readers there will find this series of books very useful.

In this book the author has given a clear and complete presentation of essential facts of the various Dasa systems. Effects of planets in Main Dasa, Antro Dasa upto prana Dasa have been discussed.



Dasa gives a system whereby we see the results which impact the native in a time period. Each Dasha is controlled by one planet. It is the disposition and relationship of this planet, that the promised events are reflected. The results which a planet promises in its Dasa has to be studied by a careful analysis of the planet.

The Vimshottari Dasha is a 120 year cycle of planetary position based on the position of Moon in one of the lunar mansions called Nakshatras. We have started the book explaining various Dasas. The first basic principles have been explained at length.

In the next part we go in details, discussing the strength of the planet depending upon position of planets, lordship and various rules that modify the strength.

Each Dasa and its predictive aspect are explained in details. It takes into consideration the sign in which the planet is posited. It also explains the effect of directional strength, state of the planet and the divisional strength. This will enable the reader to make an overall assessment of the planet whose Dasa is being analyzed for a native.

The next part dwells with the rules that have to be followed while taking the impact of Sub Period in the major period (Dasa) of the planet. We have in details discussed factors that strengthen or weaken the result which is promised. Further the impact of other vectors, like the transit and strength have been explained.

The predictive aspect for Major and Sub Period of. all planets have been dwelled in length. The results, in general for all Dasas have been explained not only for Antardasha (Sub Period) but also for Pratyantar (Sub— Sub Period), Sookshma (Sub Sub Sub Period) and Prana Dasa (Sub Sub Sub Sub Period).

To conclude an important chapter has been put which talks of the Avashtas (State) of Planets and their effects. This will be of great help in doing predictions.

This book which is the sixth book in the encyclopedia will be useful for those doing predictions as well as for the research students. A lot of research and also we have tried to cover all aspects that are required to understand the Dasa System.

Astrology is the branch of knowledge of certain mysteriously secret relationship between the Celestial bodies and terrestrial life.

Observations prove that trends in human experiences correspond to movement of the Planets in the Solar system. It is a matter of common experience that the ailments of a rheumatic or asthmatic patient are usually aggravated on 1 1th day Qf the bright or dark Moon fortnight and the new and full Moon days. Physicians all over the world as well as layman have noticed the changes of developments of labour pain on these days.

Natal astrology is the study of these relationships in regard to human life; it classifies and correlates causes and effects, thus explains the natural laws that connect stellar dynamic causations with the Native’s behaviour or the mundane events.

Life is short, Any branch of knowledge is vast, so is astrology- applied astronomy. Judgement on a Nativity is difficult, and therefore it is necessary, that a person interested in astrology should diligently read the writings of others, who have treated rationally this science, or Art of predictions and make it his business to find out the true natural causes of things by experience, to know the certain positions and procession of the planets and constellations, etc., but above all be sincere lover of truth.

There is in life of every man an instant which decides his entire future. Almost always it is chance which has taken the person like the wind does to leaf, throwing him into a new and unknown situation, where once he has entered in is obliged to obey a superior force. The person does becomes the slave of circumstances, however still free to play things according to his free will, but within the limits of strengths and weakness of the planetary configuration his birth. Well, the Dasa systems are one such method to give us timely pre-warning for pre-arming, to bring emotional, psychological and attitudinal balances in his life.

A Vedic or Hindu Dasa system is one of the unique methodologies developed by the ancient Seers. The various Dasa studies indicate certain predispositions or tendencies in human life, which sometimes, are so clear that they become virtual certainties. Experience is the great test, and had not the experience proved to the truth of the deductions of various Dasas methods.

Vimsottari Dasa corresponds to the complete circle of 360 deg, which is three times the span of maximum life- one hundred and twenty years. The Zodiacal circle when divided into twenty-seven constellation each of 13 deg 20 mm, and the life span of one hundred and twenty years when divided by nine, gives thirteen years and four months, thus there is a proportion of one deg for each year of life. Further to simplify matters, observe the starry sign where Sun, Jupiter, Saturn and Rahu with mean motion (speed) joins, upon any birth chart, and we have the clue to NAADI predictions.

The Principles of predictions are three- Logic, Sense, and Experience, but the main principles of operations are four —The Planets, the Constellations and the positions of all these in respect of one another, and the Native’s backdrop. An astrologer should be thoroughly acquainted with the complete commixtures and distinct virtues or powers of all the Planets and the Stars, and the influences of these on a Nativity, then only it will be possible to declare what will happen by or from such motions of the Heavenly bodies, and by consequence can correctly foretell future events imprinted on the mortals.

While judging the effects due to the planets in the horoscope and their successive combinations in the period, sub-period and sub-sub-period after birth, the general significations of the planets must be taken into account.

In general, it is necessary to take into consideration, when judging the effects of a planet, (1) its natural ruler-ship in the order of the signs; (2) the house (Bhava) occupied by it; (3) the house, or houses, over which it rules in the horoscope.

The judgment concerning any planet is derived from a consideration of its ruler-ship in the signs and the Bhava (houses) occupied by those signs, in addition to the place of the planet itself, its general nature, and its sympathies and antipathies in the natural world and in humans.

For this reason, the Moon is strong in the second and fourth houses; the Sun in the fifth and first; Mars in the first and eighth; Saturn in the tenth and seventh, etc., irrespective of the signs in which they are found; for they have affinity with these several houses by their affinities in the Kalapursha (world-soul), the horoscope of which is of Mesh Lagna (Aries for rising sign), during the whole of Kali Yuga (the present age), i.e., the Dark, or Iron Age.

During the Periods of a planet- As the general effects of the horoscope is derived from the configurations and conditions of all the planets, taken as natural significators for the whole life, so, in judging of the effects of any period of the life, attention must be paid to the condition (by position and configuration) of the planet ruling that period as determined by the Dasa calculation, i.e., the dividing of time (the life-period) into its periodical sub divisions i.e. periods, sub-periods, and sub-sub-periods.

Its basis is the Moon longitude at birth. According to the conition of the planets ruling the required period, the life and fortunes of the native will be affected.

During the Sub-Period of a planet- The effects are considered in relation to the general effects due to the planets governing the period in which they fall, and they are subsidiary to the effects promised by the period planet (Lord). Then, if the period-Lord shows good effects, it does so from its position and aspects at birth, and an evil sub-period-Lord cannot counteract its effect wholly, but some good will remain behind. The result is similar when, mutatis mutandis, the Period planet is evil and the Sub- Period-Lord good. But when both agree in nature and point to the same end, then the effects are forcible and decided, either for good or evil, as the case may be.

During the Sub-sub-Period- The effects are taken as subsidiary to the, sub-periods of Planets

. (The longest of these periods- Venus is over a period of 6 months 20 days, viz., the sub-sub-period, of the Sub-Period, in the Major Period (Maha Dasa); the shortest sub-sub-period is that of the Sun in its own sub-period and Major period; it lasts only 5 days 9 hours 36 minutes (Say 5 days and 10 hours). Sub-sub-sub-Periods and sub-sub-sub-sub-periods are even of much shorter durations and should be used only when birth time is accurate, and required to time an event especially important or fatality or for rectification of birth time with respect to known events.)

The condition of the sub-sub-Period-Lord must be taken into account, and its relations to the sub-period-Lord properly estimated. Its effects may then be accurately known. A few straightforward rules are necessary in order to bring the above observations into systematic form.

The Generalised Rule to Judge the Planetary periods in brief are as follows:-

1. Consider the positions and affections of the period planet properly, for even a good planet will not bear good fruit during its period, if it be ill affected by sign or position, or afflicted by the majority of malefic planets, or in divisional charts like Navamsa.

2. The sub-period planet must be considered in the same way as the period planet, but in addition thereto its relations with the period planet must be taken carefully into account; for though the planets have a natural enmity and friendship existing between them, and due to their respective natures, yet when the sub-period planet is in good aspect / relationship to the period planet it will produce good, even though these planets be natural enemies. Similarly, friendly and benefic planets will not produce good fruits, if weak or afflicted, or themselves afflicting (by position) the period planet to which they are related.

3. The effects of the ruling or karaka planets are intensified at such time as the Sun or major planets may be transiting through the signs occupied by them or the signs over which they rule.

4. The sub-sub-period planets are considered in the same manner, in regard to the sub-period planets to which they are related, as these latter are to the period planets. It thus happens that even when the period is a good one, as shown by the position and affections of the period planet, yet there are sub-periods, and again sub-sub-periods, when evils may naturally arise.

5. The general effects of the planets thus related must be taken into account, and their natural relations, as well as their temporary relations in the horoscope, must be well considered. Thus, Saturn and Sun, although natural enemies by sign and exaltation, may be respectively in Libra and Leo, in which case they are in temporary good relations, occupying the third and eleventh signs respectively from one another. Judgment is made accordingly, but it is to be understood that a temporary friendship will not entirely overcome a radical and constitutional enmity.

6. The effects will further have relation to the nature of the house corresponding to the sign occupied by the sub-period planet, in the period under consideration. Thus if the period be that of Sun, and the sub-period be that of Venus, and Venus be in the sign Aquarius, the effects will fall out in relation to the eleventh house affairs; if Venus be in Libra, then seventh house affairs will be affected.

7. The sign, counted from the Ascendant, will give a further element of interpretation. Thus if, in the sub-period of any planet, that planet occupies Leo, and Scorpio and is in ascendant, the effects will fall on the tenth house affairs.

8. The number of the signs counted from the period to the sub-period planet will give the house corresponding thereto, over which the effects will hold sway. Thus:- Sun in Virgo and Venus as sub-period planet in Scorpio will show the third house affairs to be affected.

10. The houses in the horoscope ruled by the planet whose period, sub- period, or inter-period is considered must also be regarded as affecting.

11. Rahu and Ketu (Dragon’s Head and Tail) have no houses, but transmit the influence of the signs they are in, and of the planets to which they are conjoined. The Dragon’s Head has affinity with the sign Scorpio, and the Dragon’s Tail with the sign Taurus.

12. If the inter-periods of the different sub-periods be taken into account, the above” effects” will apply equally well to those also, by counting the sub-period planet as a period planet, and the inter-period planet as a sub-period planet. In this way the prognostics serve for every period of life, from the greatest to the least, allowance being made for the relations of the significators in the minor periods. In all cases the effects due to the Lord of period are of prior importance, the sub- periods-lord and sub-sub-periods-lord following in subsidiary order.

13. During the period and sub-period of a very well disposed planet, nearly all type of benefic result is likely. Similarly, when the sub-period planet under consideration is ill disposed in all respects then the native faces all sorts of problems during that period e.g. when Mars is debilitated and badly aspected, then the spouse may suffer or the native may have a car accident or loss of property.

14. During the sub-period of two planets having an exchange of their signs in Birth chart, especial results are possible e.g. when Sun is in Capricorn and Saturn is in Leo, then during each other’s period or sub- period excellent effects are experienced pertaining to the houses and planets thus related.

15. In the major period, it is the sub-period planet which will be more effective to give results e.g. when Moon and Mars are in conjunction, then in the Moon-Mars period accident, injury, violence and such happening are more likely. But during Mars-Moon period more beneficial effects will be experienced according to the Mars lordship of houses. As Mars work as an motivator for the Moon (mind) thought and actions.

Travelling Direction<

In judging of the direction in which a person will travel, when such is shown In the horoscope, or again in the Period., Sub-Period, and sub-sub Period, effects, the following rule is usually taken:-

- The first house, with its complements twelfth and second, governs the South.

- The tenth, with ninth and eleventh, governs the East.

- The seventh, with fifth and eighth, governs the West; and

- The fourth, with third and fifth, governs the North

Therefore, Mars rules the East; the Moon rules the North; Venus governs the West; and Saturn the South.

Judgment is chiefly to be made from the houses, and next, but subserviently, from the signs occupied by the planets.

In the forthcoming chapters we are attempting to give a clear and concise presentation of the essential facts of Dasa systems, and intricacies of Vimsottari Dasa, as preached by the ancient Seers and from our own experience.
