Kaahala Yoga or Kahala Yoga
There can be two possibilities in Kahala Yoga.
1. When lord of fourth house and lord of ninth house are placed in mutual kendras and lagna and its lord is in strength.
2. When the fourth house lord is either exalted or in its own house, and is associated with or aspected by the tenth lord, Kahala yoga is formed.
Basically Kahala yoga gives importance to the 4th house and its lord more than 9th and 10th lords. Here 9th and 10th lords bring fortune and luck to the matters related to 4th house. Instead of 9th lord, a strong Jupiter also capable of strengthening the 4th house. So the person with Kahala yoga will be happy, owns huge land, property, gold etc. will be blessed with vehicles, good education. he will be very aggressive, will be commander of an army.
