Chapter 5 · Year Lord and Muntha
वर्षेशादिविचाराध्यायः
अतोन्यथा रिष्टहराः खचरा मुनिभिस्स्मृताः ॥रिष्टकर्तृग्रहाणां च वीर्य्यमेकत्र कारयेत् ॥
The sages said that the other planets, in the opposite state, remove arishta (harm in the year). One should add the strength of the planets that bring harm in one place.
Simple meaning: Planets in the opposite state remove harm. Add up the strength of the harm-making planets in one place.
तद्वच्चरिष्टहर्तृणां स्थापयेच्च पृथग्बलम् ॥
Weighing harm: set the strength of the harm-removers apart. Add the strengths for danger to life and illness to the harm side.
देहांगपुण्यजीवानां बलं तद्भंगकृद्बलः ॥
Weighing harm: the strength of body, merit and life goes to the side that breaks the harm.
तयोरंतरजो धीमान् रिष्टं तद्भंगमादिशेत् ॥
Take the difference between the two strengths. That tells whether harm stays or goes.
