Those born with the above mentioned extraordinarily long life combinations will be able to control their senses, just as the sages and chant religious hymns. They live in caves using divine medicines.
I have thus explained these Yogas, as explained by Yavanas with the help of my past deeds. The sum effects of these Yogas should be decided in various Dasha Bhuktis after a careful analysis.
Ch. 7. Ayurdayadhya
I shall now explain in a clear and careful way the method of knowing the Dasha periods for those, that are born under the Yogas stated earlier.
The numerous methods of assessing longevity have been clearly stipulated by old scholars Maya, Yavana, Siddhasena, Prabodha, Mandavya and Vishnu Gupta.
Should the Grahas commencing from Sūrya onwards remain in their highest exaltation points, they contribute 19, 25, 15, 12, 1 5, 21 and 20 years for the total longevity of the native.
The Grah, that is at its deepest debilitation degree contributes half of the above mentioned years. Should it be anywhere in between, then the number of years will have to be found by proportional calculations.
Note the difference between a Grah’s actual position and deep debilitation point and multiply this figure by the figure of Pindayurdaya year (Sloka 3 supra) and arrive at the Grah’s contribution to longevity.
Deduction for Grahas in combustion, inimical Bhavas and the visible half, that are involved in war between Grahas, or, that are close to Rahu etc., should be made only after being suitably taught by a Guru.
Amshayurdaya calculations should be made, as above and the deductions for Grahas posited in Vyaya, Labh, Karm, Dharm, Randhr and Yuvati Bhava should be made, as under: 1, ½, 1/3rd, ¼, 1/5th, 1/6th, respectively. This is in the case of malefics. For benefics, only 50% of the reduction, as above applies. Grahas lose half of their contribution, if in fall, or in combustion.
In the matter of Vyayadiharana (i.e. position in Vyaya, Labh, Karm, Dharm, Randhr and Yuvati Bhava), if both malefics and benefics are together in one Bhava, then no deduction applies to benefics. If there are two Grahas in the same Bhava, then the deduction should be only through the strongest of the two. The Grahas, except Mangal, if they occupy inimical Bhavas, lose a third of their contribution. The eclipsed Grahas lose half of their contribution except Śukr and Śani.
Those, that have lost in war between Grahas lose one third. The luminaries lose 1/12th, if they join the nodes. Notes: There is no reduction for Mangal even, if he be in an enemy’s Bhava. Sūrya is the Grah, that combusts others.
Hence, the half reduction does not apply to him apart from Śukr and Śani (as Śukr and the Śani do not lose their rays even, if they are combust (vide Uttarakalamrita). Lastly, Sūrya and Candr do not involve in war between Grahas; as such no reduction applies to them on this count. Mangal is strong even in his enemy’s Bhava.
The contribution in number of years by Lagn equals to the number of Navamshas it has passed, when counted from Mesh. If Lagn is strong and occupied by a benefic, the figure should be multiplied by one fourth and,
Notes: Suppose Lagn (be it in any Rāśi) falls in Vrischik Navamsh, its contribution is 8 years, as the Rāśi Vrischik is the 8th from Mesh. Further, this figure has to be modified thus:, if benefics are there or, if Lagn is strong (by way of Shad Bal calculations), the contribution 8 becomes 10, when one fourth is increased. Should Lagn be weak, or occupied by a malefic, then, one fourth is to be reduced, i.e the said figure becomes 6 only.
The longevity will be exactly arrived at by assessing a Grah’s exact position from its exaltation and debilitation points, if the Grah has benefic company, or, when Lagn is strong and falling in a benefic’s Bhava, or, when Yuvati Bhava is occupied.
While the system of calculating longevity by exaltation and debilitation process is common to all human beings, the difference between Dasha (i.e. periods) and Samskara (i.e. process of rectification by proper deductions) should be considered carefully.
The process of rectification, or deduction from Dasha years contributed should be made with the help of the strongest Navamsh. A wise Jyotishi shall do so after assessing the strength of the two.
Note the longitudes of the Grahas in terms of Rāśi, degrees and minutes. Multiply this by 108 and divide by 12 and the remainder will indicate the years contributed.
The multiplier is two, if the Grah is in its own Navamsh, or Dreshkan, or Rāśi, or Vargothama Navamsh. It is to be trebled, if it is in retrograde motion, or in exalted state. It should be halved, if the Grah is in fall.
The reductions for Mangal should be done here too, as explained for Pindayurdaya and, while occupying inimical Bhavas. Lagn will contribute the same number of years, as the Navamshas attained by it.
Amshaurdaya shall be resorted to, if Lagn is the strongest. Should Sūrya be the strongest, then Pindayurdaya is recommended.
Naisargikayu is adopted, if Candr is the strongest. If all the Grahas be in own Bhavas, exaltation Bhavas, or in such Navamshas, then also
Amshayurdaya is recommended. The same applies, if the Grahas are not yuti with Lagn, Sūrya and Candr.
