The Role of Dispositors
The importance of dispositors has long been recognised as an essential principle of Parashari Jyotish.
"Note the planets ruling the signs occupying the lords of 6th, 8th and 12th. If the said dispositors are in such evil houses in turn and be associated with or aspected by malefics, the native will be miserable and indigent."
And again in shloka 33-34 (Ch.36) we read;
"Note the following four planets: a) the ascendant lord, b) the dispositor of the ascendant lord, c) the dispositor of the planet at b, d) the Navamsha dispositor of the planet at c. If all these are disposed in angles and trines from the (natal) ascendant, or be exalted, Kalpadruma yoga exists. One with this yoga will be endowed with all kinds of wealth, be a king, pious, strong, fond of war, and merciful."
From these slokas we can understand the importance given to dispositors in traditional Vedic astrology. Furthermore, the importance given to amsha dispositor (in above shloka) supports the principle demonstrated >here<
Maharishi Parashara makes it clear that bhava lords have a strong influence on the houses they occupy and/or aspect; see >here<. There is never any question that bhava lords carry the significations of the houses they own - why then would we assume that the bhava lord does not (also) carry forward the influence of the grahas it disposits. This is best illustrated in the following chart, shown below in both the South Indian style and Vedic Wheel style.
Apart from the planet's position, strength, and aspects of other planets, there are two very important considerations which are often ignored when assessing the results of planets in each house.
The first of these considerations is the position and strength of the planet's dispositor, as demonstrated in following example.
This chart shows Ketu's dispositor, lagnesh Saturn, occupying 6th house of service (enemies and disease) in sign of great friend. According to scripture, Lagna (1st house) signifies our innate nature, character, psychological make-up, our general welfare, health, and our status in society (social level).
Ketu's dispositor (Saturn) well-placed in 6th denotes that the native may be drawn towards some kind of service. What kind of service might be known by considering the position and strength of Saturn's dispositor. In this instance, dispositor of Ketu's dispositor (Mercury), is enjoying exaltation in 9th house of dharma, guru, religion, Vedas etc.. Jyotish, a limb of the Vedas, is seen from this auspicious house.
Another (important) consideration when assessing the placement of individual planets is the position and strength of their nakshatra lord.
As an example, the above chart has Ketu (in lagna) occupying nakshatra of Shravana, lorded by Moon. Moon (placed in 10th house) signifies the general public whilst 10th karma bhava deals specifically with our actions in society.
Following the thread (dispositor/nakshatra) we find that Moon in 10th disposits Jupiter and Rahu, both of whom occupy nakshatra of Ashlesha (lorded by exalted 9th lord Mercury) whilst Moon, in turn, occupies nakshatra of Swati ruled by Rahu.
Move mouse over each nakshatra (below) for more information.
Negative traits may be at the forefront if nakshatra lord is weak, afflicted or occupies a dusthana.
It should also be evident how these indisputable threads, woven together, tell the story of an individual life...each story being unique to that individual alone.
