Chapter 8 · Month Chart and Monthly Results
मासप्रवेशादिविचाराध्यायः
अत्र लग्नपापग्रहयोरंशसाम्ये कर्तरीदोष इत्युक्तं गर्गेण ॥लग्नाद्विरिःफगौ क्रूरौ त्रयमेतत्समांशकम् ॥तदा कर्तरिजो दोषो नान्यथा भावजं फलम् ॥
Here Garga says that the kartari (planets on both sides) dosha (fault) comes when the lagna (rising sign) and the bad planets are equal in part. Two bad planets go to the 2nd and the 12th from the lagna. These three are equal in part. Then the fault born of kartari comes, and not otherwise. Otherwise the result is the house's own.
Simple meaning: Kartari fault only when the lagna and the two bad planets are in the same part. Otherwise the house gives its usual result.
कर्तर्यपवादोपि बादरायणोक्तः ॥
No kartari when the Moon is in the 2nd, or a good planet is there, or Jupiter is in the last house.
अत्र शुभग्रहकर्तरी शुभैव स्वल्पसौख्यकरी ज्ञेयेति ॥
A kartari of good planets is good, and gives a little happiness.
ताजिकसारे ॥
Lagna lord or Moon in the 7th: happiness. Venus in the 10th or 4th and Jupiter and Mercury: victory.
