दशाफलम्
तद्भेदेन च तत्कार्यं गतिभेदं फलं स्मृतम् ।दशेशऋक्षमारभ्य भुक्तेशर्क्षे च गुण्यते ॥ २८१३ ॥
In the full Deva Keralam this is Venkatesa 2813.
The task follows that difference. The result follows the difference in course. Start from the dasha (planet period) lord's nakshatra (star) and count to the bhukti (sub-period) lord's nakshatra. Then multiply.
Simple meaning: Count from the dasha lord's star to the sub-period lord's star.
सप्तभिर्गुणितं कृत्वा ह्यष्टभिर्भागमाहरेत् ।
After the count, the remainder gives illness, gain, travel, prison or wealth.
ऐश्वर्यमर्थनाशं च ह्यपमृत्युं तथा वदेत् ।
The last remainders give power, money loss or, the verse says, early death.
अष्टमाधिपतौ षष्ठे षष्ठेशे व्ययराशिगे ।
With the 8th lord in the 6th, the 8th lord's dasha can bring suffering.
