ग्रहराशिस्वरूपवर्षप्रवेशाद्यानयनाधिकारः
तुलादिषड्भैः सहिताः प्रकल्प्यास्तेंशकाः पुनः॥तैरंशैः सहितं लग्नं लग्नसन्धिः प्रजायते ॥
With the lagna in the six signs from Libra, they are increased by it. Take these again as degrees. The lagna (rising sign) plus those degrees is the lagna sandhi (junction between two houses).
Simple meaning: Easy method: (rising sign Libra to Pisces) add the difference to 15 instead. Use that number as degrees and add it to the rising sign: the 1st junction.
तैर्युतो लग्नसंधिश्च धनभावो भवेदिह॥
Easy method: add the same step again for the 2nd house and the 2nd junction.
तैर्युक्तो धनसन्धिश्च भ्रातृभावो भवेत्स्फुटम् ॥
Easy method: keep adding the step for the 3rd house and the 3rd junction.
तृतीयसन्धिस्तैर्युक्तस्तुर्यभावः प्रजायते ॥
Easy method: one more step gives the 4th house; the rest as before.
