Chapter 5 · Year Lord and Muntha
वर्षेशादिविचाराध्यायः
अयमर्थः ॥ जन्मतो गतवर्षसमूहे द्वादशभक्ते शेषे जन्मलग्नाद्यत्र धनसहजादिभावे विश्रामं प्राप्नोति स एव मुथहास्यादिति ॥
This is the meaning. Divide the total of years gone since birth by twelve. Count the remainder from the janma lagna (rising sign at birth). The house where it comes to rest is the muntha (the point that moves one sign each year). It may be the 2nd house, the 3rd house and so on.
Simple meaning: Finding the muntha: years gone divided by 12, remainder counted from the birth lagna.
जन्मचक्रे प्रत्यब्दमेकराशिभ्रमणवशाद्यत्र राश्यादिभावं याति स भाव एव वर्षे मुथहा स्यादिति तट्टीकाकृत् ॥
Muntha by the commentator: it moves one sign a year, and the house it reaches is that year's muntha.
तेजास्सिंहोपि ॥
Muntha moves one house a year, starting from the birth lagna.
वामनोपि ॥
Muntha is one sign a year, starting from the sign of the birth lagna.
