Divisional Charts — What They Are & How D10 Is Derived

What Are Divisional Charts?

Planets, signs and houses have been covered. The missing piece is the divisional charts — Varga Chakras. Parashara gives 16 in Brihat Parashara Hora Shastra. Other scholars, such as Jaimini and the Tājika scholar Nilakantha, give more. The class keeps to Parashara's.

How they are made:

• The Rasi chart divides the 360° zodiac into 12 parts and maps each 30° to one Rasi
• A divisional chart divides each Rasi further into N equal parts and maps each part back to one of the 12 Rasis by Parashara's formula
• Every divisional chart has the same 12 Rasis, but the planets may be in totally different positions

Notation: D10 = Dasamsa, the 10th division. D9 = Navamsa (9 parts). D24 = Chaturvimsamsa (24 parts).

Formulas: They are in BPHS and in PVNR's book Vedic Astrology: An Integrated Approach. You do not need them by heart — his software gives all 16 charts once the date, time and place are entered.

D-10 Dasamsa — Derivation Rule

Amsa means division. Dasamsa = 10th division. Each Rasi is divided into 10 parts of 3° each.

Mapping rule:

• Odd (male) Rasis — Aries, Gemini, Leo, Libra, Sagittarius, Aquarius: count from that Rasi itself. The ten Dasamsas of Aries go to Aries, Taurus, Gemini … Capricorn.
• Even (female) Rasis — Taurus, Cancer, Virgo, Scorpio, Capricorn, Pisces: count from the 9th from that Rasi — from its dharma.

Example 1: Sun at 17° Leo

1. 17 ÷ 3 = 5⅔ → five parts are over; the Sun is in the 6th part
2. Leo is odd → count from Leo itself
3. Leo(1) → Virgo(2) → Libra(3) → Scorpio(4) → Sagittarius(5) → Capricorn(6)
4. Sun is in Capricorn in D-10

Example 2: Mars at 22° Scorpio

1. 22 ÷ 3 = 7⅓ → seven parts are over; Mars is in the 8th part
2. Scorpio is even → count from the 9th from Scorpio = Cancer
3. Cancer(1) → Leo(2) → Virgo(3) → Libra(4) → Scorpio(5) → Sagittarius(6) → Capricorn(7) → Aquarius(8)
4. Mars is in Aquarius in D-10

What Do Divisional Charts Show?

The Rasi chart is strictly about the body — physical existence.

• The 10th house of the Rasi chart shows the work a person does at the physical level. It does not necessarily tell you the career.
• A great businessman may work very hard. Physically there is no difference between him and a construction worker. Both may have the same Rasi chart. The Dasamsa differs: one is engaged in business, the other slogs for his daily bread.
• Physically a businessman only signs papers, reads papers, runs somewhere, talks to people. What he is doing mentally — working out a business strategy — is not in that.

Divisional charts show the environments in which the body operates.

• Career is an environmental thing. Unless you know the environment a person operates in, you cannot know what he is doing.

"Rasi chart is strictly about body, physical existence. Other divisional charts, they show subtle things about you. They don't necessarily show what is physically happening to you."
