There is another method of Ayurdaya enumerated by Jeevasarma. I now detail the same in the following verses.
Note the longitudinal distance between a Grah’s position and its deep fall degree. Convert this into minutes and divide by 21600. The quotient will reveal the years contributed. The remainder should be multiplied by 12 and divided again by 21, the quotient is months. Again multiply the latest remainder by 21600. The days are represented by the quotient. Multiply the latest remainder by 60 and the quotient will yield Ghaties. Notes: If the Grah is past its debilitation point and be towards its exaltation, then the longitudinal distance be calculated from deep fall to its position.
Reduce 17 year I month 22days 8 Ghaties and 34 Vighaties, if the Grah is close to its exaltation. Should it be close to its debilitation, then add a similar figure.
The deductions do not apply to Śukr and Śani, if they are eclipsed and also to Mangal in his enemy’s Bhava. Lagn’s contribution is equal to the number of Navamshas it attained. A malefic there in reduces the figure by one fourth and a benefic there in increases the figure by one fourth. According to Jeevasarma, Grahas in Dhan and Vyaya Bhava from Lagn and Grahas in the 2nd and the 12th from Candr, all Grahas near their debilitation point, those, that are devoid of strength and those in Lagn, or in Yuvati Bhava will reduce the contribution to one seventh of the total life.
Now, about Trinal reduction (Trikon Shodhana) with reference to Ashtak Vargas. First draw a Kundali of Rāśis, as usual. Mark benefic dots of Ashtak Varg of the Grah required and then Trikon reductions should be made.
Notes: The author now deals with the Bandhu system of assessing longevity. For detailed calculations of Ashtak Varg system refer to works, like Brihat Jataka, Saravali, Dr. B.V. Raman’s Ashtak Varg System of Predictions etc. Simultaneously, Ch. 17 infra may also be seen. For the purpose of deductions take the sets of Mesh and its Konas, Vrishabh and its Konas, Mithun and its Konas and Kark and its Konas In each set, whichever is the least, put the same in the other two. If one of the three is vacant, no change should be made in the other two. If two Rāśis are vacant, then the third one should also be made dotless. Lastly, if all the three Rāśis are equal with dots, vacate dots in all the three Rāśis.
The above is the method of trinal reductions. Now the method of reduction to the pairs of Rāśis, which have common lords is explained below. This is called Ekadhipathya Shodhana. This reduction is applicable, when there are benefic dots in both the Rāśis owned by a Grah. Should there be less number of dots in a Rāśi, while the other Rāśi (of the same Grah) is not occupied, the smaller number of dots shall be used for both the Rāśis. If the occupied Rāśi has more dots than the occupied Rāśi, then make the dots nil in the unoccupied Rāśi. (The occupation can be by any Grah) Similar reduction applies, when there are equal number of dots in both the Rāśis owned by a Grah, but one of them should be free from occupation.
Should both the Rāśis be occupied, no reduction shall be made. Should there be the same number of dots in both the Rāśis, which are not occupied, dots should be made nil in both the Rāśis. If one of the Rāśis is vacant in respect of dots, retain dots in the other Rāśi. The rules for Ekadhipathya Shodhana do not apply to Kark and Simh.
Notes: The suggestions given in Slokas 32-37 are for reductions applicable to two Rāśis owned by one Grah and are called Ekadhipathya reductions,
The final figures in each Rāśi, after effecting trinal reduction as well, as Ekadhipathya reduction, as above, be multiplied by the concerned Rāśi multipliers and, if a particular Rāśi is occupied the figure must be multiplied by the respective Grah’s multiplier. The Rāśi multipliers from Mesh onwards are: 7, 10, 8, 4, 10, 5, 7, 8, 9, 5, 11 and 12, respectively. ‘The figures of multiplication for Guru, Mangal, Śukr and Budh are 10, 8, 7 and 5, respectively.
The multiplier is 5, or other Grahas (i.e. for Sūrya, Candr and Śani). The multipliers for Rāśis and Grahas should be treated separately. The dots in the 12 Rāśis, obtained after Trinal and Ekadhipathya reductions should be multiplied by Rāśi multipliers individually. Should a Rāśi be occupied by a Grah, the dots should be multiplied by Grah Gunakara.
The Rāśi figure and Grah figure (as obtained through process explained in Slokas 38-40½) should be added in respect of each Grah, together. (This can be called Shodya Pinda. This Pinda should be multiplied by 7 and divided by 27. The quotient is years of longevity by the Grah concerned. Multiply the remainder by 27 to get months. The next remainder is multiplied by 30 and divided by 27 to get days. The latest remainder is multiplied by 60 and divided by 27 to get Ghatis. 27 years make one Mandala and so the years in excess of 27 (for each Grah) should be rejected.
Notes: According to Sambhu Hora, if the contribution of years is in excess of 27, but less than 54, then subtract the quotient from 54. If the quotient is more than 54, subtract it from 81 and, if above 81 subtract from 108.
The contribution of each Grah should be worked out, as explained in the Slokas above.
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 enemy’s 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.
