Chapter 5 · Year Lord and Muntha
वर्षेशादिविचाराध्यायः
मणित्थोपि ॥द्विचन्द्र १२ भक्ताश्च गताब्दपिण्डाश्शेषेन्थिहा स्यादथ जन्मलग्नात् ॥भ्रमेण युक्ता मुथहा पुराणैश्शुभाशुभस्यापि निरूपणाय ॥
Manittha also says this. Divide the years gone by twelve. The remainder, counted from the janma lagna (rising sign at birth), is the muntha (the point that moves one sign each year). The old teachers give it, joined with its going round, to judge good and bad.
Simple meaning: Finding the muntha: years gone divided by 12, remainder counted from the birth lagna.
ताजिकतिलकेपि ॥
Muntha enjoys one house of the chart each year.
एतत्स्पष्टङ्गणितपूर्वंकमुक्तन्ताजिकमुक्तावल्याम् ॥ ॥
Exact muntha: years gone plus one, divided by 12, remainder counted from the birth lagna. Each month it moves a twelfth of a house.
या मुन्थहायाः खलु मासभुक्तिर्गतैष्यमासान्तरवासरैस्ताम् ॥
Muntha's daily motion: divide its monthly motion by the days in the month.
