अथ धनर्णं लग्नानयने विशेषः ॥सूर्योदयाद्यातघटीषु भोग्यैर्दिवावशेषे रसभार्कभुक्तैः ॥निशागते व्यङ्गयुतार्कभोग्यैर्निशावशेषे रविभुक्तभागैः ॥गतागतैराश्युदयैः स्वभोक्त्या लग्नं धनर्णं सममेव भूयादिति ॥
Now a special point in finding the lagna (rising sign) by plus and minus. For ghatikas (24-minute units) gone since sunrise, use the Sun's degrees still to go. For time left of the day, use the degrees passed of the Sun plus six signs. For time gone in the night, use the degrees to go of the Sun plus six signs. For time left of the night, use the Sun's degrees passed. Go through the risings of the signs gone or to come, with the part used. The lagna by plus and minus comes out just the same.
Simple meaning: Rising sign by plus and minus: from sunrise or sunset count forward, before them count back. Both ways give the same rising sign.
अथ दशमलग्नानयनम् ॥
Finding the 10th house: start from the Sun's time passed or to go in its sign, using equator rising times and the time from midday.
क्रमाद्गतैष्यानुदयांश्च शेषमशुद्धहृत्खाग्निगुणं लवाद्यम् ॥
10th, 7th and 4th houses: the 10th from the time from midday; add six signs to the rising sign for the 7th, and to the 10th for the 4th.
अथ पूर्वनतेपि धनलग्नानयनार्थं मदीयं वृत्तम् ।
Balabhadra's shortcut for the 10th house: with eastern time from midday, use the time from midnight and the Sun plus six signs.
