ग्रहराशिस्वरूपवर्षप्रवेशाद्यानयनाधिकारः
अत्रलग्नादिभावा अन्वर्थसंज्ञा ज्ञेयाः ॥ यथादेहविचारोलग्नात् द्रव्यविचारो द्वितीयादेवं सर्वत्र ॥ एतत्सविशेषभावविचारे वक्ष्यामः ॥
Here the houses from the lagna (rising sign) have names that mean what they say. For example, the body is judged from the lagna, wealth from the 2nd. It is so for all. We will tell this in the section on judging the houses in detail.
Simple meaning: 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.
चरेण संयुतोनाश्च कर्तव्यास्तिथिनाडिकाः ॥
Half-day: 15 ghatikas plus the day-length difference (Aries to Virgo) or minus it (Libra to Pisces). Half-night: 30 less the half-day.
