The sixteen divisions

Varahamihira used six divisions of each sign. The BPHS uses sixteen (shodashavarga) (6.2–4), each a chart of its own read for a particular matter.

How each is counted (BPHS 6)

D Name Size of part Rule Read for (7.1–8)
1 Rashi 30° the sign itself the body
2 Hora 15° odd signs: Sun's half then Moon's; even signs the reverse (6.5–6) wealth
3 Drekkana 10° the sign, its 5th and its 9th; presided over by Narada, Agastya and Durvasa (6.7–8) siblings
4 Chaturthamsa 7°30′ the lords of the four kendras from the sign (6.9) fortune
7 Saptamsa 4°17′ odd signs from the sign; even signs from its 7th (6.10–11) children
9 Navamsa 3°20′ movable signs from the sign; fixed from its 9th; dual from its 5th (6.12) the spouse
10 Dashamsa 3° odd signs from the sign; even from its 9th; the ten guardians of the directions preside (6.13–14) power and position
12 Dvadashamsa 2°30′ from the sign itself (6.15) parents
16 Shodashamsa 1°52′30″ movable from Aries, fixed from Leo, dual from Sagittarius (6.16) vehicles
20 Vimshamsa 1°30′ movable from Aries, fixed from Sagittarius, dual from Leo (6.17–21) worship
24 Chaturvimshamsa 1°15′ odd signs from Leo, even from Cancer (6.22–23) learning
27 Saptavimshamsa 1°06′40″ "from Aries and the other movable signs" (6.24–26) strength and weakness
30 Trimshamsa unequal odd: Mars 5°, Saturn 5°, Jupiter 8°, Mercury 7°, Venus 5°; even reversed (6.27–28) evils
40 Khavedamsa 45′ odd from Aries, even from Libra (6.29–30) auspicious and inauspicious effects
45 Akshavedamsa 40′ movable from Aries, fixed from Leo, dual from Sagittarius (6.31–32) all matters
60 Shashtyamsa 30′ double the degrees in the sign, divide by 12, add 1 to the remainder (6.33–41) all matters

Where the text needs a convention

The research behind this website found several places where the BPHS (in the transcription read) does not fully settle the rule:

  • D27: "from Aries and the other movable signs" is usually read as fire signs from Aries, earth from Cancer, air from Libra, water from Capricorn — an interpretation.
  • D30: the BPHS names the lords and deities of the five parts, not the signs, so placing them in a chart needs a convention.
  • D60: whether to count from the sign itself or from Aries is disputed; the 60 parts are named (Ghora, Rakshasa, Deva ... Indurekha), in order for odd signs and reversed for even, and are benefic or malefic (6.33–41).

A careful astrologer states the convention used.

Classes of dignity (BPHS 6.42–53)

A planet in a "good" division — its exaltation, moolatrikona or own sign — in several divisions earns a named class. In the ten-division scheme: 2 good divisions Parijata, 3 Uttama, 4 Gopura, 5 Simhasana, 6 Paravata, 7 Devaloka, 8 Brahmaloka, 9 Airavata, 10 Sridhama; the six- and seven-division schemes and the sixteen-division scheme have their own names. Divisions of a combust, defeated or weak planet do not count (6.42–53).

The twenty-point strength (BPHS 7.17–27)

Vimshopaka bala scores a planet out of 20 across a set of divisions. Each scheme has weights adding to 20 (7.17–27):

Scheme Weights
Six divisions D1 6, D2 2, D3 4, D9 5, D12 2, D30 1
Seven D1 5, D2 2, D3 3, D7 2½, D9 4½, D12 2, D30 1
Ten D1 3, D60 5, the other eight 1½ each
Sixteen D1 3½, D60 4, D9 3, D16 2, D2 1, D3 1, D30 1, the other nine ½ each

In each division the planet scores by its relation to the sign's lord: own 20, great friend 18, friend 15, neutral 10, enemy 7, great enemy 5. The total is Σ (weight × score ÷ 20).

Reading the result: under 5, the planet cannot give good results; 5–10, some; 10–15, middling; over 15, fully favourable.

Summary

  • Sixteen divisions, each with a counting rule and a matter (6.2–41; 7.1–8).
  • D27, D30 and D60 need a stated convention.
  • Planets dignified in several divisions earn named classes (6.42–53).
  • Vimshopaka bala scores a planet out of 20 with four schemes of weights (7.17–27).

Exercises

  1. Which division is read for career and position? For children?
  2. From which sign do the navamsas of a fixed sign begin?
  3. What is the Vimshopaka weight of the navamsa in the six-division scheme?
  4. A planet scores 20 in every one of the six divisions. What is its Vimshopaka?

Answers: 1. D10 (dashamsa); D7 (saptamsa). 2. From its 9th sign (6.12). 3. 5. 4. 20 × 20 ÷ 20 = 20.
