Phaladeepika
स्वोच्चत्रिकोणस्वहितारिनीचे पूर्णं त्रिपादार्द्धपदाल्पशून्यम् । क्रमाच्छुभं चेदशुभं विलोमाट् मूढे ग्रहे नीचसमं फलं स्यात् ॥ ३०॥
The good influence of planets is at its maximum, three quarters, a half, a quarter, at its minimum or nil according as the planets are in the exaltation sign, Moolatrikona, Swakshetra, friendly sign, inimical sign or depression sign respectively. The proportions given above are with respect to benefics or lords of benefic houses. In the case of malefics, or lords of malefic houses, it will be reverse. When a planet is in combustion (conjunction with the Sun), its effect will be similar to that in depression.
