ஆயுள் - பிருஹத் பராசர ஹோர சாஸ்திரம்

14-15. Lagn’s Contribution. The number of years, contributed by Lagn, will correspond to the number of Rasis it gained (from Mesh), while the degrees Lagn has gained in the particular Rasi will also correspondingly donate (30° = l year). If the Lagn’s Lord in the Navans is stronger than Lagn’s Lord, then the contribution should be computed only based on the number of Navansas gained (from Mesh), otherwise the computation will be for the Rasi Lagn.

16-17. Nisargayu. O Brahmin, now I tell you about Nisargayu. 1, 2, 9, 20, 18, 20 and 50 are the years, allotted to Candr, Mangal, Budh, Sukr, Guru, Surya and Sani from the period of birth.

18-19. Ansayu. Now I will tell you about Ansayu contributions by Lagn and Grahas. The years correspond to the number of Navansas, counted from Mesh. Multiply the longitude in question by 108. If the product exceeds 12, expunge multiples of 12 and consider the final product in Rasis, degrees etc., as years, months etc.
