Amshaurdaya shall be resorted to, if Lagn is the strongest. Should Surya 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, Surya and Candr.

There is another method of Ayurdaya enumerated by Jeevasarma. I now detail the same in the following verses.

Note the longitudinal distance between a Grahs 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 Sukr and Sani, if they are eclipsed and also to Mangal in his enemys Bhava.
