ग्रहराशिस्वरूपवर्षप्रवेशाद्यानयनाधिकारः
सन्धिराश्यादितुल्यो ग्रहः पूर्वापरभावसन्धिस्थरेखायामेव स्थाप्यः ॥
A planet equal to a sandhi (junction between two houses) in sign, degree and so on is placed right on the sandhi line. That is the line between the earlier and the later house.
Simple meaning: Planet exactly on a junction: draw it on the line between the two houses.
अथ च भावकुण्डली केवलंभावफलार्थैव अन्यस्सर्वोपि ताजिकविचारो ग्रहकुण्डल्यैव विधेय इति प्राञ्चः ॥
House chart vs planet chart: the house chart is only for house results; all else from the planet chart.
अथ भावविंशोपकानयनमुक्तं मुक्तावल्याम्॥
House score: gap from planet to junction, divided by gap from house to junction. A third of it is the score out of 20.
अत्रान्तकरणे विशेष उक्तः पद्धतौ ।
Which junction to use: planet before the middle of the house, use the first junction; past it, use the later junction.
