दशानयनाधिकाराध्यायः
पृथक्पृथग्दृष्टिकलादिकेन वर्षादिसंख्याद्युमुखन्निहन्यात् ॥भजेद्दगैक्येन च तन्मतेन लब्धं दशाहाद्युफलेननाड्यः ॥
Write each planet's look separately, in minutes and so on. Multiply it by the count of days in the year, and so on. Divide by the total of all the looks. By this rule, the result is the period in days. For the day's result, it comes in ghatikas (24-minute units).
Simple meaning: Tasira periods, working: each planet's look times the year's days, divided by the total of the looks, gives its days.
अत्र लग्ननिरीक्षका ग्रहा हीनांशक्रमेण दशाप्रदास्स्युरिति ताजिकसारोक्तिर्न युक्तिसहा यतस्तासीरदशा दृष्टिमूलभूता दृष्टिरहितस्याल्पांशखेटस्य सबलस्यापि दशाभावात् ॥
Tasira periods: they go by the look on the lagna, not by least degrees. A planet with no look gets no period.

Tasira periods, year example: looks of 50, 40, 30, 20 and 10 share 360 days as 120, 96, 72, 48 and 24.
