जातकम् २
यश्च मूर्तितनुग्लावो वृद्धिगः स्वोच्चभस्थितः ।स्वत्रिकोणसुहृद्भस्थस्तस्य मध्यमसत्फलम् ॥ १४७ ॥
In the full Narada Purana (Purva Bhaga) this is chapter 55, verse 147.
A planet in the 1st house, the 11th or its high sign gives a middling good result. So does one in its mulatrikona (a planet's strong own-sign part) or a friend's sign. (Our text is unclear here: one word, perhaps a name of the Moon.)
Simple meaning: A planet in the 1st or 11th, or in a high, own or friend's sign, gives middling good.
श्रेष्ठं शुभतरं वाच्यं विपरीतगतस्य तु ।
Well-placed planets give the best results. Badly placed ones bring much bad and little good.
चरे सन्मध्यदुष्टाभ्यामंगभंगे विपर्ययात् ।
The result depends on which third of the rising sign it is and whether the sign moves, stays fixed or is dual.
स्वामीज्यज्ञयुता होरा दृष्टा वा सत्फलावहा ।
A rising sign with its lord, Jupiter or Mercury gives good results. Bad planets on both sides spoil it.
