Stellar Astrology (Nadi Astrology) is a predictive system of astrology which gives importance to houses, constellation & sub lord signified by a planet depending upon its degree in the astrological chart. In this system, a planet gives results not on the basis of its natural significations or the houses it owns but on the combination of houses signified by the planet, its constellation lord & the sub lord. A single house is not capable of giving any result & it is very difficult to assess results of a planet without looking at its constellation lord & sub lord. For eg: Second house signifies a number of things but we cannot pinpoint anything unless we see the other houses that the planet is signified through itself, star lord or sub lord. If the planet is also signifying the eleventh house, then either it can mean "Gain/Addition of a member in the family" or "Gain of money & assets" - those who follow astrology knows the second house
Sun is a luminary and it is the only source of light, energy & heat we have in this solar system. Sun rules on our soul and it is only because of the Sun that this solar system & life is possible. Since, Sun is so important in our birth chart therefore in whichever house the Sun goes, it will surely brighten that house & will have a huge impact on that house and on our personality as well. In Nadi Astrology , we never give any important to the placement of any planet in any house. Every time we wish to find out the events a planet can trigger in the native's life we apply the Rules of Nadi Astrology on that planet.
