கிரகக் கதிர்களின் விளைவுகள் - பிருஹத் பராசர ஹோர சாஸ்திரம்

1-2. The sage said. O Brahmin! Now I am going to tell you about the number of rays of the Grahas. When Surya etc. are in their deep exaltation point, their rays are: Surya 10, Candr 9, Mangal 5, Budh 5, Guru 7, Sukr 8 and Sani 5. The rays are nil, when these Grahas are in deep debilitation, the number of rays would be proportionate with the number of Rasi. The following method is to be adopted for ascertaining the proportionate number of rays. Deduct the debilitation Rasi etc. of the Grah, whose rays are to be ascertained, from his longitude. If the remainder is less than 6 Rasis it should be multiplied by the number of rays of that Grah, mentioned above and the product should be divided by 6. The result will denote the number of rays of that Grah. In case after deduction the remainder is more than 6 Rasis, then it should be deducted from 12. The other procedure will remain the same.
