भावानां नामान्युक्तानि ताजिकमुक्तावल्याम् ॥तनुर्धनंभ्रातृसुहृत्सुतारिस्त्रीरंध्रधर्माः क्रमशो विलग्नात् ॥व्यापारलाभव्ययसंज्ञकाश्च संहारगत्या स्युरिमेर्कतुल्या इति ॥
The names of the houses are given in the Tajikamuktavali. In order from the lagna (rising sign), they are: body, wealth, brother, friend, son and enemy. Then come wife, randhra (8th house), dharma (right duty), work, gain and loss. These are twelve, and they run the reverse way.
Simple meaning: Names of the 12 houses: body, wealth, brother, friend, son, enemy, wife, 8th, duty, work, gain, loss.
अत्रलग्नादिभावा अन्वर्थसंज्ञा ज्ञेयाः ॥ यथादेहविचारोलग्नात् द्रव्यविचारो द्वितीयादेवं सर्वत्र ॥ एतत्सविशेषभावविचारे वक्ष्यामः ॥
House names mean what they say: body from the 1st, wealth from the 2nd, and so on.
तत्र भावानयनोपायउक्तः ॥ अथ चरखंडदिनार्द्धनयनं ।
Day-length steps: take the noon shadow at the equinox, multiply it by 10, 8 and 10, and divide the last by 3.
स्यात्सायनोष्णांशुभुजर्क्षसंख्यचरार्द्धयोगो लवभोग्यघातात् ॥
Day-length difference: add the day-length steps for the signs passed and a share of the next one. That gives it in palas.
