Chapter 7 · Finding the Dashas
दशानयनाधिकाराध्यायः
अथोक्तानान्दशाकदम्बानां विषयविभागो निरूप्यते ॥ ग्रन्थान्तरे ॥बली यदा हीनबलो ग्रहः स्यात्तदा तु हीनांशदशा विधेया ॥सर्वग्रहालोकनलब्धवीर्य्ये तनौ तसीराख्यदशा प्रदिष्टा ॥ १ ॥
Now the use of each of the dasha (planet period) systems given above is set out. In another text: when the planet with the least degrees is strong, use the hinamsha dasha (period by least degrees). When the lagna (rising sign) gains strength from the look of all planets, the tasira dasha (period by the planets' looks on the lagna) is taught.
Simple meaning: Which period system to use: least-degree planet strong, the least-degree system. Lagna seen by all planets, the tasira system.
लग्नस्य सबलत्वे हि भावपूर्वा तु सा मता ॥
Lagna strong: use the house tasira periods. Hour lord strong: use the hour-lord periods.
हद्दाख्या वर्षलग्नस्य हद्देशे बलसंयुते ॥
Year lagna's hadda lord strong: use hadda periods. Year Moon strong: use natural periods.
सवीर्यजन्मराशीशे मुद्दा गौरीमतेन तु ॥
Birth sign lord strong: use Gauri's mudda periods. All planets equal in strength: use tasira periods.
