अंशोद्भवं लग्नबलात्प्रसाध्य- मायुश्च पिण्डोद्भवमर्कवीर्यात् । नैसर्गिकं चन्द्रबलात्प्रसाध्यं ब्रूमस्रयाणामपि वीर्यसाम्ये ॥ २८॥
Amsayurdaya is to be calculated upon the predominance in strength of the Lagna; Pindayurdaya upon the Sun's superiority in strength and Naisargikayurdaya when the Moon's power is strongest. We shall now state what should be done when the the three (Lagna, the Sun and the Moon) are of equal strength.
