Chapter 7 · Finding the Dashas
दशानयनाधिकाराध्यायः
अथ भावतसीरदशा तत्रैव ॥शोध्यलग्नादयो भावास्स्वीयस्वीया प्रभावतः ॥पृथक् पृथक् शेषांशास्ते कल्प्यादिवसाः क्रमात् ॥ २ ॥
Next, the house tasira (a Tajika word for a planet's influence) dasha (planet period), in the same text. Take the houses, from the lagna (rising sign) on. Take each one away from the next, each by its own. The degrees left for each are taken as its days, in order.
Simple meaning: House periods: the degrees between one house and the next give that house's days.
लग्नादीनामथैतेषां सौरसावनतोक्तवत्॥
House periods: turn their solar days into solar-civil days. This is called the house order.
अत्र प्रकारांतरंतत्रैवोक्तम्।
House periods, another way: the degrees between houses, times 300, divided by the sign's rising time.
दिनाद्या लग्नपूर्वाणां स्वस्वामिफलदायकाः॥
House periods: each house's period gives the results of that house's lord.
