D27 chart (Bhamsha, Nakshatramsha): the map of your strengths and stamina

What is the D27 Bhamsha in Vedic astrology?

The D27 is one of the sixteen charts Parashara describes in the Brihat Parashara Hora Shastra, the founding text of Vedic astrology: the Shodashavarga. Like all divisional charts, it cuts each sign of your birth chart into equal parts and gives each part a sign: a new wheel, with its own Ascendant and houses, that zooms in on one area of life.

Its name tells you its subject. In Sanskrit, bha means a star, a lunar constellation, in other words a nakshatra; amsha means a part. The Bhamsha is the part of the stars, and Nakshatramsha says the same thing with the word nakshatra. It is also called Saptavimshamsha, the twenty-seventh part. Parashara assigns it strengths and weaknesses: where the D1 draws the whole of life, the D27 shows what in you goes the distance and what needs to be spared.

How is the D27 chart calculated?

Each 30° sign is divided into 27 parts of 1°06′40″. Parashara’s rule counts these parts continuously from Aries: the first part of Aries goes to Aries, the second to Taurus, and so on around the zodiac. At the end of a sign, the count carries on into the next one instead of starting over. Since 27 parts make two full rounds plus three signs, each element gets its own starting point:

• Fire signs (Aries, Leo, Sagittarius): the first part goes to Aries.
• Earth signs (Taurus, Virgo, Capricorn): the first part goes to Cancer.
• Air signs (Gemini, Libra, Aquarius): the first part goes to Libra.
• Water signs (Cancer, Scorpio, Pisces): the first part goes to Capricorn.

The degree in the D27: the planet’s degree within its sign, multiplied by 27, minus the full rounds of 30°. A Moon at 5° Taurus falls in the fifth part of Taurus (from 4°26′40″ to 5°33′20″); counting from Cancer, that fifth part is Scorpio. 5 × 27 = 135, which leaves 15° once four rounds are removed: the Moon is at 15° Scorpio in the D27.

How the D27 relates to the 27 nakshatras

The zodiac holds 27 nakshatras, the lunar mansions of 13°20′; the D27 cuts each sign into 27 parts. The parallel goes further: one D27 part is exactly one twelfth of a nakshatra. Each nakshatra therefore contains twelve parts, and because the count starts from Aries, those twelve parts run through the whole zodiac, from Aries to Pisces, in every one of the 27 mansions.

The same logic applies to the padas, the quarters of a nakshatra, 3°20′ each: every pada contains three D27 parts. The first pada of any nakshatra gives Aries, Taurus, then Gemini; the second, Cancer, Leo and Virgo; the third, Libra, Scorpio and Sagittarius; the fourth, Capricorn, Aquarius and Pisces. The D27 is a zoom inside the nakshatra: it shows where, within its lunar mansion, each planet stands.

What do you look at in a D27 chart?

The D27 reads like a full wheel: an Ascendant, houses counted as whole signs from it, planets in signs. Its question never changes: what holds, and what tires? Four markers:

• The D27 Ascendant and its ruler: the way you take hits and the way you recover. A well-placed ruler gives bounce; a ruler in difficulty asks you to pace your effort.
• Dignities: a planet exalted or in its own sign in the D27 keeps its strength over time; debilitated, it gives fast, then runs out of breath, and needs to be spared.
• The Sun, the Moon and Mars: the Sun speaks of vital force and confidence, the Moon of emotional resilience and the ability to bounce back, Mars of stamina and courage under effort.
• The gap with the D1: a planet that shines in the D1 but is weak in the D27 impresses and wears itself out; a planet that is discreet in the D1 but strong in the D27 holds when the others let go.

Uranus, Neptune and Pluto appear on the wheel, set back: classical Vedic astrology reads only the seven visible planets and the lunar nodes, Rahu and Ketu, always facing each other.

An example of a D27 reading

Take a generic chart. Mars is at 14° Cancer in the D1, the sign of its debilitation: drive turns cautious there, and action runs through emotion. In the D27, this Mars falls in the thirteenth part of Cancer; counting from Capricorn, the count goes all the way round the zodiac and comes back to Capricorn, its sign of exaltation, at 18°. Reading: behind a fighting spirit that looks hesitant, real stamina, the kind that carries long projects to the end. The lever: trust that endurance rather than the feeling of the moment.

Same chart, a Moon at 5° Taurus, exalted in the D1: the mood looks steady, people count on you. In the D27, it moves to Scorpio, its sign of debilitation. That steadiness comes at a price: emotions are absorbed deep down rather than digested, and tiredness arrives without warning. The lever: regular time to withdraw, soothing routines, and the right to say it is too much before you are forced to.

The method: compare each planet’s dignity in the D1 and the D27, then look at your Vimshottari dashas: a strength or a fragility of the D27 is felt most when its planet rules the current period.

What birth time accuracy does the D27 need?

An exact time, to within a few minutes. The Ascendant changes sign every two hours on average; in the D27, it changes roughly every 4 min 30 (two hours divided by 27), a little faster or slower depending on the sign. A time rounded to the quarter hour can therefore give another D27 Ascendant, and other houses.

The Moon itself depends on the time: it moves about half a degree an hour and changes part, and therefore D27 sign, roughly every two hours. The Moon at 5° Taurus in the example would be in Libra two hours earlier, in Sagittarius two hours later. The other planets move more slowly: a few hours rarely shift them by a whole part.

Without a birth time, the Vedic charts are switched off on the site: the Ascendant and the houses depend on it. In France, the full copy of the birth record (copie intégrale) shows the time. If yours is rounded, calculate the chart five minutes earlier and five minutes later: if the D27 Ascendant changes, read the planets’ dignities first, as they depend less on the time, before the houses.

How to open the D27 chart on the site

The D27 sits on the page of your chart, next to the Western wheel, which stays the default view:

1. Calculate your birth chart with your date, place and exact time of birth.
2. At the wheel, choose Vedic (sidereal): the D1 (Rasi) opens, calculated with the Lahiri ayanamsa.
3. In the list of twenty divisional charts, choose D27.
4. Read the wheel and the positions: the sign, degree and house of each planet, with the line that recalls what the chart is about.

A D27 strength is confirmed elsewhere: read it with the D1 and the Navamsha. That is the site’s method for every reading: crossing the charts, never reading just one.
