दशानयनाधिकाराध्यायः
उक्तञ्च ताजिकसारे ॥वीर्ये समाने तनुखेटयोश्चेत्स्यातान्तदा लग्नपखेटयोश्च ॥यस्याऽल्पभुक्तिः खलु पूर्वकोसौ ज्ञेयो ग्रहज्ञैरिह पाकमार्गे इति ॥
And it is said in the Tajikasara. Say the lagna (rising sign) and a planet are equal in strength. Then look at the lagna lord and the planet. The one with the smaller daily motion comes first. Astrologers should know this in the order of the periods.
Simple meaning: Lagna and a planet tie: Tajikasara agrees. The slower of the lagna lord and the planet comes first.
गतेरपि साम्ये उक्तवल्लग्नेशग्रहयोर्मध्ये पूर्वोदितस्याद्या दशा उदयसाम्येपि कथितपाठक्रमेण दशाक्रमो ज्ञेय इति ॥
Lagna and a planet still tied: the one that rose first comes first; then the usual listing order.
अथमासप्रवेशे दशानयनमुक्तं मुक्तावल्याम् ॥
Month periods: divide the month's length by the total of remainders, then multiply each remainder by it.
हीनांशकानुक्रमतो यथास्थलवैक्यहन्मासमिते यदाप्तम् ॥
Month periods, another way: divide the month by the total of the degrees as they stand, then multiply each by the result.
