Phaladeepika
सुहृदरिपरकीयस्वर्क्षतुङ्गस्थितानां फलमनुपरिचिन्त्यं लग्नदेहादिभावैः । समुपचयविपत्ती सौम्यपापेषु सत्यः कथयति विपरीतं रिःफषष्टमेषु ॥ १८॥
The fullness or otherwise of the effects of planets occupying the 12 houses, viz., Lagna, 2 nd, 3 rd, etc., must be judged by a consideration of the exact nature of the sign occupied by the planet, ie., whether it is a friendly or an inimical sign or the house of a neutral planet, or whether the planet in question is occupying his own, or his exaltation Rasi. Satyacharya, however, says that benefics posited in any house generally promote the advancement or prosperity of that house while malefics in any house work only its decay. This is reversed in the case of the 6 th, the 8 th and the 12 th houses.
