दृष्टिसाङ्गबलेष्टकष्टाद्यानयनाधिकारः
अत्र शुभस्थानगे ग्रहे शुभफलं रूपमितं स्थाप्यं ॥ अशुभस्थानगे ग्रहे अशुभफलं रूपमितं स्थाप्यं पुनश्शुभाऽशुभफलयोरंतरेकृते सति यच्छुभमशुभंवा अवशिष्टन्तदेव ग्रहस्य इष्टं कष्टंवा फलन्दशाफलादिषु ज्ञेयम् ॥
Here, for a planet in a good place, set a good result measured as one rupa (unit of strength). For a planet in a bad place, set a bad result measured as one rupa. Then take the good and bad results from each other. Whatever is left, good or bad, is that planet's ishta (good strength) or kashta (bad strength) result. This is to be known in the dasha (planet period) results and the rest.
Simple meaning: Ishta and kashta: give one unit to the good result and one to the bad result. Subtract. What is left is the planet's good or bad result.
एतत्स्पष्टमुक्तम्मर्णितथेन ॥
Manittha: set one unit apart for the good result, and one unit for the bad result.
पृथक्स्थितस्यास्य यदन्तरालम्फलं तदेवाभिधमत्र वेद्यम् ॥
Ishta and kashta: the gap between the good and bad share is the result. Above ten it is full, below ten it is middle.
कष्टाधिके पूर्णशशाङ्क १० हीने शुभे च कष्टे दशतो वरिष्ठे ॥
Ishta and kashta in the dasha: when the bad share is more than ten and the good share is less than ten, the dasha result is worse than bad.
