Chapter 5 · Year Lord and Muntha
वर्षेशादिविचाराध्यायः
ताजिकतिलकेपि ॥अशेषजन्मोदयपूर्वभावचक्रेन्थिहैकम्भवनम्भुनक्ति ॥
Tajikatilaka also says this. In the whole wheel of houses, starting from the janma lagna (rising sign at birth), the muntha (the point that moves one sign each year) enjoys one house.
Simple meaning: 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.
प्रसूतिलग्नभ्रमणेन भावान्मन्थातीत्यवदन्यादवोप्यनुकूलः ॥ केचन सर्वत्र जन्मलग्नांशयोजनङ्कुर्वन्ति ॥ तत्पूर्वोक्तवाक्यानां विचारेण युक्तिसहं ॥
Yadava agrees on the going round. Some add the degrees of the birth lagna, and that is reasonable.
