The contribution of a Grah should be halved, if it is yuti with another Grah. Similar halving should be done, if a Grah is debilitated, or eclipsed. For a Grah posited in an enemys Bhava, the loss is one third. This applies also to those in the visible half of the Zodiac, those, that have lost in war between Grahas and those, that are in the Pata range of the luminaries. When a Grah warrants repeated deductions, then, only the highest should be done. The figures for all the Grahas should be added together and multiplied by 324 and divided by 365. The net longevity is equal to the quotient in the process.

Notes: The above reductions are explained thus. Suppose Budh has contributed 12 years, the reductions are, as under: a) If he is along with another Grah, in the Rasi Kundali, then his contribution is halved, i. e. only 6 years; b) If Budh is combust, or in Neech, then also half is deduced. (Combustion need not necessarily occur, when Surya is in the same Rasi. Only the longitudinal distance counts. Suppose Budh is in 28 degrees of Simh, while Surya is in 2 degrees of Kanya. Even then Budh is combust). c) If Budh in the example is in his enemys Bhava, then one third reduction should be made, i.e. 12 is reduced to 8. d) If it is in the visible half of the zodiac, then also 1/3^rd should be rejected. Visible half means the area from Lagn BhavaMadhya to 7^th BhavaMadhya counted backwards. According to Dr. B.V. Raman; the reduction for malefic Grahas in the visible half should be done, as under: 12^th Bhava: Full, 11^th 1/4^th, 10^th 1/3^rd, 9^th 1/4^th, 8^th 1/5^th and 7^th l/6^th. He continues to say, that for benefics 50% of the above should be applicable for the 6 Bhavas. e) One third reduction is made, if a Grah is involved in war. (War does not apply to Surya and Candr) f) One third reduction should be made, if a Grah is involved in Rahugrasta Surya, or Candr Grahanas. Pata means Rahus path. Hence Pata range of Surya and Candr is interpreted, as above. g) Only the highest reduction should be enforced, if a Grah attracts more than one reduction, as mentioned from a toe above. In such case, only half is reduced once. But according to Dr. Raman, there is full reduction in the case of a malefic in Vyaya Bhava from Lagn, which of course can be done only once.
