1-4. SIXTEEN DIVISIONS OF A SIGN - VARGAS:
Dasamamsa, Dvadasamsa, Shodasamsa, Vimsamsa, Chaturvimsamsa, Sapthavimsamsa, Trimsamsa, khavedamsa, Akshavedamsa, and Shashtiamsa.
5-6. RASI AND HORA:
The Rasi owned by a planet is called its Kshetra (one sign).
The first half of an odd sign is the Hora ruled by the Sun while the second half is the Hora of the Moon. The reverse is true in case of an even sign. Half of Rasi is called Hora. These are totally 24 counted from Aries and repeat twice (at the rate of 12) in the whole of the Zodiac.
One third of a Rasi is called Drekkana (decanate). these are totally 36, counted from Aries (to Pisces), repeating thrice at the rate of 12 per round. The 1st, 5th, and the 9th Rasis from a sign are its three decanates, and are respectively lorded by Narada, Agasthya, and Doorvasa.
The lords of the 4 angles from a sign are the rulers of respective Chathurthamsa of a Rasi commencing from Aries. Each Chathurthamsa is one fourth of a Rasi. The deities respectively are Sanaka, Sananda, Kumara, and Sanatana.
The Sapthamamsa (one seventh of a Rasi) counting commences from the same sign in the case of an odd sign. It is from the seventh sign thereof while an even sign is considered. The names of the seven divisions in odd signs are: Kshara, Ksheera, Dadhi, Ghritha, Ikshu Rasa, Madhya, and Suddha Jala. These designations are reversed for an even sign.
The Navamsa calculation are for a movable sign from there itself, for a fixed sign from the 9th thereof, and for a dual sign from the 5th thereof. They go by designations Deva (divine), Manushya (human), and Rakshasa (devilish) in successive and repetitive order for a moveable sign. (Manushya, Rakshasa, and Deva are the order for a fixed sign while Rakshasa, Manushya, and Deva are the dual sign's order.)
Starting from the same sign for an odd sign and from the 9th with reference to an even sign, the 10 Dasamsas each of 3 are reckoned. These are presided over by the ten rulers of the cardinal directions viz. Indra, Agni, Yama, Rakshasa, Varuna, Vayu, Kubera, Isana, Brahma, and Anantha in the case of an odd sign. It is in the reverse order that these presiding deities are reckoned when an even sign is given.
The reckoning of the Dvadasamsa (one twelfth of a sign or 2 1/2 degrees each) commences from the same sign. In each sign the presidentship repeats thrice in the order of Ganesa, Aswini Kumara, Yama, and Sarpa for the 12 Dvadasamsas.
Starting from Aries for a movable sign, from Leo for a fixed sign and from Sagittarius for a dual sign, the 16 Shodasamsas (16th part of a sign, i.e. 1¡52'30") are regularly distributed.
The presiding deities of these repeat in the order Brahma, Vishnu, Shiva, and Sun four times in the case of odd sign. It is reverse in the case of an even sign that these ruling deities are understood.
From Aries for a movable sign, from Sagittarius for a fixed sign and from Leo for a common sign - this is how the calculations of Vimsamsa (1/20th of a sign or 1¡30' each) are to commence. The presiding deities of the 20 Vimsamsas in as odd sign are respectively: Kaali, Gauri, Jaya, Lakshmi, Vijaya, Vimala, Sati, Tara, Jvala-Mukhi, Sveta, Lalita, Bagala-Mukhi, Pratyangira, Sachi, Raudri, Bhavani, Varada, Jaya, Tripura, and Sumukhi.

The Siddhamsa (1/24th part of sign or 1¡15' each) distribution commences from Leo and Cancer respectively for an odd sign and an even sign. In the case of an odd sign the ruling deities repeat twice in the order od Skanda, Parsudhara, Anala, Viswakarma, Bhaga, Mitra, Maya, Antaka, Vrisha-dhwaja, Govinda, Madana, and Bhima. reverse these from Bhishma (to Skanda) twice to know the deities for the Siddhamsa in an even sign.
24-26. BHAMSA (NAKSHATRAMSA OR SAPTAVIMSAMSA):
The Bhamsa lords are respectively the presiding deities of the 27 Nakshatras as under: Dastra (Aswini Kumara), Yama, Agni, Brahma, Chandra, Isa, Aditi, Jiva, Ahi, Pitara, Bhaga, Aryama, Surya, Tvashta, Marut, Sakragni, Mitra, Vasava, Rakshasa, Varuna, Visvadeva, Govinda, Vasu, Varuna, Ajapa, Ahirbudhanya, and Pusha. These are for and even sign. The Bhamsa distribution commences from Aries and other moveable signs for all the 12 signs.
The Trimsamsa lords for an odd sign are Mars, Saturn, Jupiter, Mercury, and Venus. Each of them in order rules 5,5,8,7, and 5 degrees. The deities ruling over the Trimsamsas are respectively, Agni, Vayu, Indra, Kubera, and Varuna. In the case of an even sign, the quantum of Trimsamsa, planetary lordship, and deities get reversed.
(1/40th part of a sign): For odd signs count from Aries and for an even sign from Libra in respect of Chatvarimsamsas (each of 45' of arc). Vishnu, Chandra, Marichi, Tvashta, Dhata, Siva, Ravi, Yama Yaksha, Gandharva, Kala, and Varuna repeat successively as presiding deities in the same order for all signs.
31-32. AKSHA VEDAMSA:
(1/45 th part of a sign): Aries, Leo and Sagittarius are the signs from which the distributions respectively commence for moveable, immoveable, and common signs. In moveable signs, Brahma, Siva, and Vishnu; in immovable signs Siva, Vishnu, and Brahma; and in common signs Vishnu, Brahma, and Siva repeat 15 times the presidentship over these Ashavedamsas.
(1/60th part of a sign or half adegree each): To calculate the Shashtiamsa lord, ignore the sign position of a planet and take the degrees etc. it traversed in that sign. Multiply that figure by 2 and divide the degrees by 12. Add 1 to the remainder which will indicate the sign in which the Shashtiamsa falls. The lord of that sign is the planet ruling the said Shashtiamsa. In odd signs, the names of Shashtiamsas are: 1. Ghora, 2. Rakshasa, 3. Deva, 4. Kubera, 5. Yaksha, 6. Kinnar, 7. Bhrashta, 8.

42-53. VARGA CLASSIFICATION:
Maitreya, explained now are the sum effects of classifications of different divisions (or Vargas so far narrated). These are four kinds, viz. Shad Varga (6 divisions considered), Saptha Varga (7 divisions considered), Dasa Varga (10 divisions considered), and Shodasa Varga (all the 16 divisions considered).
In the Shadvarga classification, the Varga designations are Kimsuka, Vyanjana, Chaamara, Chartra, and Kundalal according to a planet being in 2 to 6 combinations of good Vargas. Next is the Saptha Varga in which these classifications continue in the same manner up to six combinations of good Vargas, the 7th additional Varga getting classified as Mukuta.
In the dasa Varga scheme, the designations commence from Pasrijata, etc., such as two good Vargas - Parijatha, 3. Uttama, 4. Gopura, 5. Simhasana, 6. Paaravata, 7. Devaloka, 8. Brahmaloka, 9. Sakravahana, and 10. Vargas - Sridhama.
In the Shodasa Varga Scheme the combinations of Vargas go with designations thus: two good Vargas - Bhedaka, 3. Kusuma, 4. Nagapushpa, 5. Kanduka, 6. Kerala, 7. Kalpavriksha, 8. Chandanan Vana, 9. Poornachandra, 10. Uchchaisrava, 11. Dhanvantari, 12. Suryakanta, 13. Vidruma, 14. Sakrasimhasana, 15. Goloka, and 16. Vargas - Sri Vallabha.
In these divisions, the divisions falling in the planet's exaltation sign, Moolatrikona sign, own sign, and the signs owned by the lord of an angle from the Arudha ascendant are all to be considered (as good Vargas).
The divisions of a combust planet, defeated planet, weak planet, and a planet in bad Avasthas like Sayana be all ignored to be auspicious, for these destroy the good yogas.
