Phaladeepika
द्विस्थानाधिपतित्वमस्ति यदि चेन्मुख्यं त्रिकोणर्क्षजं तस्यार्द्धं स्वगृहेऽथ पूर्वमुभयोर्यत्तदृषादौ वदेत् । पश्चद्भावमिहापरार्द्धसमये युग्मे गृहे युग्मजं त्वोजस्थे सति चौजभावजफलं शंसन्ति केचिज्जनाः ॥ ११॥
In the case of a planet owning two houses, that house which happens to be the Moolatrikona one will predominate and its effects alone will be felt in full while the effects of his own house will be half. The effects of both the Bhavas will come to pass in the Dasa of the planet, the first half of the Dasa-period being monopolised by the effects of the Bhava that comes first in order. This is the opinion of some. There are others who hold that a planet posited in an odd house will have the effect of that house felt first while the one that occupies an even house will have its effect in the first half of the Dasa
