दशाफलम्
साधने योगमित्याहुः प्राबल्यं मनुरब्रवीत् ।दशेशाक्रान्तनक्षत्राज्जन्मर्क्षान्तं च गुण्यते ॥ २८११ ॥
In the full Deva Keralam this is Venkatesa 2811.
In a Sadhana (6th, success) dasha (planet period), they say, there is gain. Manu said it brings strength. Count from the nakshatra (star) the dasha lord occupies up to the birth nakshatra, and multiply the count.
Simple meaning: A Sadhana star dasha brings success; a counting method between stars follows.
सप्तभिर्गुणितं चैव स्वष्टभिर्भागमाहरेत् ।
Multiply the star count by 7, divide by 8, and the remainder gives the result.
तद्भेदेन च तत्कार्यं गतिभेदं फलं स्मृतम् ।
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.
