दशाफलम्
समन्दमान्दिरन्ध्रेशनवांशपतयो ग्रहाः ।तेषां यो दुर्बलः खेटः सुखनाशप्रदो भवेत् ।रन्ध्रे वा कष्टभे वापि गोचरे चार्कनन्दने ॥ ३०४६ ॥
In the full Deva Keralam this is Achyuta 3046.
Take Saturn, Mandi (son of Saturn, a shadow point) and the 8th lord. Take also their navamsha (one-ninth part of a sign) lords. A weak planet among them takes away happiness. This happens when Saturn moves through the 8th or through a kashtabha (sign of hardship).
Simple meaning: A weak planet of this group can take away happiness when Saturn transits a hard sign.
षष्ठेशस्य फलाध्याये फलविस्तार उच्यते ।
The 5th star's lord gives nothing in its dasha; the 4th star's lord gives great happiness.
साधने योगमित्याहुः प्राबल्यं मनुरब्रवीत् ।
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.
