It is said that Jupiter spoils the effects of the  house in which it sits and increases the effects of the houses which it aspects. Similliarly Saturn increases the effects of the house in which it is placed and spoils the effects of the houses it aspects. My question is that what if Jupiter is placed in it's own house or the house of it's exaltation and what if Saturn is aspecting it's own house or the house of it's exaltation.
For e.g. if Jupiter is placed in 6th house that means it will spoil the effects of 6th house that means the person doesn't have to fear disease or enemies but what if 6th house is own house or exaltation house for Jupiter?  

K N Rao's chart has exalted Jupiter in tenth house, what would you conclude from this ?

that's what my question is?

Hi Janvien ji,
Jupiter is called "Swa sthan hanta"...thus it harms the house it is placed but not in the case if thats his own house or house of exhaltation.
Similarly Saturn or in that case any planet if aspecting its on house will not harm it though aspect of saturn might delay the process but for good only.Aspect of saturn on its own house wont spoil the house.Infact JN Bhasin ji has gone to the extend of saying that this is "rule of thumb" that planet aspecting its own house will BE  GREATLY BENEFITED FROM IT.
