The Law of Excitation (Late) Thakur Thanwar Das, Advocate, Jhalawar (Rajsthan)

Published in Astrological Magazine somewhere before 1971

In this article I propose to deal with the Law of Excitation as applied to Vimshottary Dasha. According to the Western system of Astrology this Law has been stated as follows:

“If at the time a progressed body is in aspect to another by direction, either of the bodies forms an aspect by transit with either of the two directional bodies, then the transit will excite the directions into immediate operation.” It is claimed that this law is one of the most useful and exact in Astrology. The west has several systems of directions, the primary, the secondary, the tertiary and the radix system etc. And I for my part know how the above law is applied in practice, specially when according to their methods several directions usually operate simultaneously.

The Indian Astrologer, by and large, is satisfied with the working of the Vimshottary system, and I make bold to say that the Vimshottary is the greatest discovery yet made by any man in the field of prognostication. It is simple to calculate and is designed to give far superior results in comparison to any other method.

As stated above the Law of excitation deals with the transit position of directional lords at a given moment. Our law of excitation, to be stated below, is based on a different though equally valid principle. It will be seen that the effects of the dasha lords depend upon and vary in accordance with the strength or weakness of dasha lords while in transit. I must admit that we are apt to forget this rule in practice as, generally speaking, we depend upon the more generalized effects given in text books. The life readings that are prepared by the astrologers do not give these transit influences and while interpreting these readings we usually omit the transit of dasha lords out of consideration and thus we are likely to commit mistakes. Hence it is incumbent upon us never to presume a period or epoch good or bad unless we have consulted the ephemeris of Panchanga for the required time and examined the transit positions of the dasha lords then.

It is true that while interpreting dasha results we take into account, as per traditional method, the transit of all the nine planets as calculated from the sign occupied by the Moon in the radical map. We consider that if a planet is in exaltation, in a friendly sign, or upachaya (3rd, 6th, 10th or 11th) and has more benefic dots in Ashtak-varga that planet will give good results, and if a planet is in the rest of the houses, in debilitation or unfriendly house, it forebodes evil.

However a little reflection will show that if a certain period of our life is permeated with the influences generated by a certain major lord and also a sub-lord it is reasonable to assume that the transit influences of these very lords will dominate during that period and the other transits will play a subordinate role. Again in Vimshottary the major periods range from 6 years to 20 years and minor periods from 3 months and 18 days to 3 years and four months but neither in the entire period of any dasha lord nor in any whole sub-period uniform or monolithic effects are experienced. At a certain time the good or bad effects of a dasha planet get excited, or flare up and at other times they are lulled up or lie dormant. Therefore there must be some rule or law to explain these variations in the same period and no doubt the law on the subject has been laid down by our seers. The law may be stated as follows:

Subject always to the strength and the character of the planet in the radical map:

(a) A sub lord will excite favourable results if he is transiting his exaltation, own or a friendly sign or in trine from the major dasha lord.


(b) A sub dasha lord will excite unfavourable results if while transiting, he

(i)    becomes combust,

(ii)   is in debilitation,

(iii)  is in an unfriendly sign,

  • is posited in the 6th 8th or 12th rasi (sign) from the major dasha lord provided

                    he is not in exaltation,(see clause (a) above).


(c) The houses affected at the moment of transit will be the houses owned and occupied by him in the radical map and the house he is transiting.


(d) The transiting Moon will yield favourable results when passing through the exaltation rasi of the dasha lord, or the rasi owned by the dasha lord, or latters’ friendly rasi or when she is transiting 3rd, 5th, 6th, 7th, 9th, 10th or 11th rasi from the dasha lord. Otherwise she is unfavourable. But these are minor transits.

This is not to say that we have to be oblivious of the positions of the major Dasha lord who is also incessantly coursing through the zodiac. The above rule (a) and (b) equally apply to the major Dasha lord.

The validity of Vimshottary system may further be tested by the following almost exact law with regard to the transits of the Sun.

While considering transits we often come across the statement that we need only consider the transits of the slow moving planets, viz., Mars, Jupiter, Saturn, Rahu and Ketu. Yet no satisfactory reasons are adduced for the omission of the transits of the Sun, whom we extol as the light of all lights, the lord of constellations, the planets and the stars and the lord of twelve rasis. In the famous verse of Ramayana, Valmiki refers to the affliction to the King’s nakshatra (constellation) by the Sun, Mars and Rahu. Is it a long step from nakshatra to nakshatra dasha? It is my experience that the transit of the Sun is of prime importance and we can not afford to omit it. It is a fundamental rule of dasha interpretation that the dasha lords channel their influences through the planets connected with them by position or aspect. While interpreting the transit results of the Sun vis-à-vis the dasha planets we observe that the transit of Sun over the rasis occupied or owned by the planets aspecting or on conjunction with the dasha planets and the rasis in opposition to such aspecting planets bring into excitation the effects of the dasha planets (i.e., Dasha lord and Bhukti lord).

The rule about the transit of the Sun as the exciting cause has been tested on scores of horoscopes and has been found to work with a fair degree of exactness. Therefore while predicting


(1) Please examine the radical chart in accordance with the rules given in the classical books.


(2) Note the signs and degrees of the planets in the radical chart and find out their corresponding English dates.


(3) Examine the positions of the dasha planets from day to day and predict in accordance with rules summarized as (a), (b), (c) and (d) above. These rules have been drawn from the texts given by Satyacharya, Venkatesh, Dhundiraj and others. The effects of dasha planets will vary in accordance with such positions but within the limits permitted in the radical chart. Note also the afflictions and favourable aspects to these planets.


(4) Please examine the transits of the Sun and if you want a fair degree of exactitude the results will be noticed as culminating when the Sun passes over the sensitive points as shown above.


(5) The degree of the ascendant and the tenth house should also be noted. Note the lords of the two points and whenever the Dasha or sub-dasha of these lords are in progress the transit of the Sun over these points would provide a fillip to the effects indicated by these points.
