Verse 1 — Annual Muntha Progression & Calculation
स्वजन्मलग्नात् प्रतिवर्षमेकैकराशिभोगान् मुथहाभ्रमोतः । स्वजन्मलग्नं गतवर्षयुक्तं सा भमुखेन्थिहा स्यात् ॥ ६६ ॥
svajanmalagnāt prativarṣamekaikarāśibhogān muthahābhramotaḥ | svajanmalagnaṃ gatavarṣayuktaṃ sā bhamukhenthihā syāt || 66 ||
The Muntha progresses exactly one sign (30°) per completed year of life, starting from the natal Ascendant (Janma Lagna). Its placement in the annual chart indicates the primary focal department of life for that year.
