இராசியின் பதினாறு பிரிவுகள் - பிருஹத் பராசர ஹோர சாஸ்திரம்

1. O Maharishi Parasar, I have known from you about the Grahas, Rasis and their descriptions. I desire to know the details of various divisions of a Rasi, will you please narrate.

2-4. Names of the 16 Vargas. Lord Brahma has described 16 kinds of Vargas (Divisions) for each Rasi. Listen to those. The names are Rasi, Hora, Dreshkan, Chaturthans, Saptans, Navans, Dashans, Dvadashans, Shodashans, Vimshans, Chaturvimshans, Saptavimshans, Trimshans, Khavedans, Akshavedans and Shashtians.

5-6. Rasi and Hora. The Rasi, owned by a Grah, is called its Kshetra. The first half of an odd Rasi is the Hora, ruled by Surya. While the second half is the Hora of Candr. The reverse is true in the case of an even Rasi. Half of a Rasi is called Hora. These are totally 24, counted from Mesh and repeated twice (at the rate of 12) in the whole of the zodiac.

7-8. Dreshkan. One third of a Rasi is called Dreshkan. These are totally 36, counted from Mesh, repeating thrice at the rate of 12 per round. The 1^st, 5^th and the 9^th Rasis from a Rasi are its three Dreshkanas and are, respectively, lorded by Narada, Agasthya and Durvash.

9. Chaturthans. The Lords of the 4 Kendras from a Rasi are the rulers of respective Chaturthans of a Rasi, commencing from Mesh. Each Chaturthans is one fourth of a Rasi. The deities, respectively, are Sanak, Sanand, Kumar and Sanatan.

10-11. Saptans. The Saptans (one seventh of a Rasi) counting commences from the same Rasi in the case of an odd Rasi. It is from the seventh Rasi thereof, while an even Rasi is considered. The names of the seven divisions in odd Rasis are Kshaar Ksheer, Dadhi, Ghrith, Ikshu, Ras, Madhya and Suddh Jal. These designations are reversed for an even Rasi.

12. Navans. The Navans calculation are for a Movable Rasi from there itself, for a Fixed Rasi from the 9^th thereof and for a Dual Rasi from the 5^th thereof. They go by designations Deva (divine), Manushya (human) and Rakshasa (devilish) in a successive and repetitive order for a Movable Rasi. (Manushya, Rakshasa and Deva are the order for a Fixed Rasi, while Rakshasa, Manushya and Deva are a Dual Rasi’s order)

13-14. Dashans. Starting from the same Rasi for an odd Rasi and from the 9^th with reference to an even Rasi, the 10 Dashansas, each of 3 degrees, are reckoned. These are presided over by the ten rulers of the cardinal directions, viz. Indra, Agni, Yama, Rakshasa, Varuna, Vayu, Kuber, Isan, Brahma and Ananth in case of an odd Rasi. It is in the reverse order, that these presiding deities are reckoned, when an even Rasi is given.

15. Dvadashans. The reckoning of the Dvadashans (one twelfth of a Rasi, or 2½ degrees each) commences from the same Rasi. In each Rasi the presidentship repeats thrice in the order of Ganesh, Ashvini Kumar, Yama and Sarpa for the 12 Dvadashansas.
