The meaning of a house is principally influenced by two planets: its ruler and its karaka (significator). A karaka is the planet, which rules the matter under consideration.
Karakas
Planets (Grahas) have a set of characteristics that change according to the closeness of the planet to the end of the sign. The closer to the end of the sign the more important the Graha
Atma Karaka: The Graha that is in the highest degree is called the Atma Karaka – the significator of the self. With a significant influence on your deepest nature.
Your deepest nature will be _________________ .
The dispositor of your Atma Karaka is the Amatya Karaka that signifies Ministership in your chart. Thus your deepest nature is influenced by _______________ .
The other Karakas cannot predominate over the Atma Karaka if the Atma Karaka is strong and well placed, then the afflictions of the other Karakas cannot prevail.
