Chapter 7 · Finding the Dashas
दशानयनाधिकाराध्यायः
त्यक्त्वारिरंधान्त्यमतोन्यतो ज्ञे निन्द्योपि सोर्द्धम्फलदो दशायाम् ॥याति त्वसौ मध्यबलश्शुभत्वं संपूर्णवीर्य्योतिशुभो निरुक्तः ॥ ५ ॥
Leave out the 6th, 8th and 12th houses from the lagna (rising sign). Mercury in any other house, even when blameworthy, gives half the result in its dasha (planet period). At middle strength it turns good. At full strength it is called very good.
Simple meaning: Mercury's period by house from the lagna: outside the 6th, 8th and 12th, even a blameworthy Mercury gives half. Middle strength is good, full strength very good.
वामनः ॥
Mercury's period at full strength (Vamana): comfort and wealth from service, money, fame and power.
धर्मसिद्धिन्तु कर्माप्तिमतुलामुन्नतिन्तथा ॥
Mercury's period at middle strength (Vamana): right living, work, a great rise, money from reading and writing.
देशाद्देशांतरप्राप्तिं घातम्बंधुकुलक्षयम् ॥
Mercury's period with lost strength (Vamana): moving from place to place, injury, family loss, trouble from poor thinking.
