Amsas explained.
In Chapter I (Definitions And Elementary Zodiacal Principles), we have referred to the six modes of di vision of the Ecliptic known as Shadvarga. Certain writers have four more divisions known as Saptamamsa, Dasamsa, Shodasamsa and Shashtyamsa. These ten divisions of the Ecliptic are known as Dasavarga.
Saptamamsa is the division of a sign of the Zodiac into 7 equal parts. The lords of the 7 parts of the odd signs are respectively the lords of the 7 signs of the Zodiac commencing from the odd sign; and the lords of the 7 parts of the even signs are respectively the lords of the 7 signs of the Zodiac beginning from the 7th sign from the even sign.
Dasamsa is the division of a sign of the Zodiac into 10 equal parts. The lords of the 10 parts of the odd signs are respectively the lords of the 10 signs of the Zodiac commencing from the odd sign, and the lords of the 10 parts of the even signs are respectively the lords of the 10 signs commencing from the 10th sign from the even sign.
Shodasamsa is the division of a sign of the ecliptic into 16 equal parts. The lords of the 16 parts of the odd signs are the lords of the 12 signs commencing from the odd sign together with Brahma, Vishnu, Rudra and Surya; the lords of the 16 parts of the even signs are the lords of the 12 signs commencing from the even sign together with Surya, Rudra, Vishnu and Brahma.
Shashtyamsa is the division of a sign of the ecliptic into 60 equal parts. The 60 parts of the odd signs are those of
1. | Ghora. | 21. | Padma. | 41. | Kalinasa. |
2. | Rakshasa. | 22. | Lakshmi. | 42. | Mukhya. |

10. | Agni. | 30. | Mandatmaja. | 50. | Indumukha. |
11. | Maya. | 81. | Mrityu. | 51. | Pravina. |
12. | Pretupureesa | 32. | Kala. | 52, | Kalagni. |
13. | Apampati. | 33. | Davagni. | 53. | Dandayudha. |
14. | Devaganesa. | 34. | Ghora. | 54. | Nirmala. |
15. | Kala. | 35 | Amaya. | 55. | Subha. |
16. | Ahi. | 36. | Cantaka. | 56. | Asubha. |
17. | Amritamsa. | 37. | Sudha. | 57. | Atisitala. |
18. | Chandra- | 38. | Amrita. | 58. | Sudha. na. |
19. | Mridu. | 39. | Poornachandra | 59. | Payodhibhrama- |
20. | Komala. | 40. | Vishapradigdha | 60 | Mndurekha. |
And the 60 parts of the even signs are the above in the inverse order; that is, beginning from Indurekha and ending in Ghora.
Now, a planet which occupies his particular house, Navamsa, Dwadasamsa, Trimsamsa, etc, is said to be in his Varga. A planet occupying two Vargas is said to be in Parijatamsa; if he occupies three Vargas, he is said to be in Uttamamsa; if four vargas, in Gopuramsa; if five vargas, in Simhasanamsa; if six, in Paravatamsa; if seven or eight, in Devalokamsa; if nine, in Airavatamsa; and if ten, in Vaiseshikamsa.
