Chapter 7 · Finding the Dashas
दशानयनाधिकाराध्यायः
अत्र वर्षे भावदशात्रैलोक्यप्रकाशे उक्ता॥तन्वादिभांकगुणिताब्धि ४ दिनाद्रिरामनाड्यो ४।३७ दशास्तनुमुखेंशवशाद्भवन्ति॥तासां व्ययारिमृतिगस्य न शोभना स्याद्वर्षे दशाश्च सरलान्धिषणे जगादेति ॥१॥
In the year, the house periods are stated in the Trailokyaprakasha. Multiply 4 days and 37 ghatikas (24-minute units) by the sign number of each house from the 1st. These are the periods, from the 1st house on, by its degrees. Of these, the period of a house in the 12th, 6th or 8th is not good in the year. So Dhishana said plainly.
Simple meaning: House periods, Trailokyaprakasha: 4 days 37 ghatikas times the house number. The periods of the 6th, 8th and 12th houses are not good.
अथ वर्षे कालहोरादशा॥उक्तं च मुक्तावल्याम्॥
Kalahora periods: each planet gets one seventh of the year, in the order of the hour lords.
वारप्रवृत्तेर्गतनाडिकास्तु द्विघ्नाशरा५ प्तागतकालहोरा ॥
Kalahora at the year start: ghatikas since the weekday began, doubled and divided by five, give the hours passed.
आद्या दशा तस्य परा परेषान्तत्षष्ठषष्ठक्रमतोखिलानाम् ॥
Kalahora order: the current hour lord first, then every sixth planet. The remainder gives the parts passed and to come.
