When Rahu and Ketu are strong in a Bhava, or when they are related to the owner of that sign by conjunction, mutual aspect, or exchange, they give results independently. The effects of other planets do not come in their way. They acquire the strength of the Jord of the house in which - they are posited. The good and bad results of the bhava they occupy are to be interpreted in the light of the strength of the lord of that house.
