Phaladeepika
दुःस्थानपस्तदितरस्वगृहस्थितश्चेत् स्वक्षेत्रभावफलमेव करोति नान्यति मन्दो मृगे सुतगृहे यदि पुत्रसिद्धिः षष्ठाधिपतकृतदोषफलं च नात्र ॥ २९॥
If the lord of a Dussthana should occupy another house of his own, he will produce (in his Dasa) the effects of only that house occupied by him as Swakshetra and not the effects due to the Dussthana. For example, if Saturn should occupy Makara identical with the 5 th Bhava, there will be the acquisition of sons, and the untoward effects due as owner of the 6 th house will not happen
