What is Vedic astrology? Jyotish explained simply

What is Jyotish?

The Sanskrit word jyotish comes from jyoti, light: it is the study of the bodies that light up the sky and of what they say about a life. In India, Jyotish is one of the six Vedangas, the “limbs” of the Vedas, which serve to understand and practise them; it is called “the eye of the Vedas”, because it gives the right moment for the rites.

A graha (“that which seizes”) is a planet: the Sun, the Moon, Mars, Mercury, Jupiter, Venus, Saturn, and the two nodes of the Moon, Rahu and Ketu. A rashi is a sign, a bhava a house, and the lagna the Ascendant, the sign rising in the east at your birth. These are the building blocks of any birth chart, put together with other rules.

Where does Vedic astrology come from?

Its roots lie in the Vedas, the oldest sacred texts of India, where the course of the Sun and the Moon sets the calendar of the rites. The oldest treatise that survives, the Vedanga Jyotisha, is a calendar manual. Natal astrology was built afterwards, passed down from teacher to student over the centuries.

The founding text is the Brihat Parashara Hora Shastra (“the great treatise on horoscopy of Parashara”), attributed to the sage Parashara. It contains almost everything the site calculates: the signs and the houses, the sixteen divisional charts, the Vimshottari dashas and the yogas, the planetary combinations that shape a life.

The sage Jaimini, to whom tradition credits the Jaimini Sutras, left a second method, written in very short formulas: planets ranked by degree that become the karakas, the “significators” of the soul, of the career or of the spouse. In the sixth century, Varahamihira gathered the knowledge of his time in the Brihat Jataka. These sources are read together, just as My Birth Chart crosses the charts.

The pillars of Vedic astrology

Seven ideas make up the heart of the method. Each one has its own page, if you want to go further:

• The sidereal zodiac: the signs are aligned with the stars, not with the seasons. The gap with the Western zodiac, the ayanamsa, is about 24° today; the site uses Lahiri’s, the official Indian reference. The full comparison: tropical or sidereal.
• The nine grahas: the seven planets visible to the naked eye and the two nodes of the Moon, Rahu and Ketu, always facing each other. Uranus, Neptune and Pluto are not part of the classical reading.
• Whole-sign houses: the sign of the Ascendant is the whole first house, the next sign the second house, and so on.
• The [nakshatras](vedique:nakshatras): twenty-seven “lunar mansions” of 13°20′, each with its ruling planet and its deity, divided into four padas (quarters) of 3°20′.
• The [divisional charts](vedique:themes-divisionnels): each sign is cut into parts to build one chart per area of life: the D9 for partnership and dharma, the D10 for career, and so on up to the D60, the chart of karma.
• The [dashas](vedique:dashas-vimshottari): planetary periods that divide up a life; the Vimshottari cycle lasts a hundred and twenty years and starts from the nakshatra of your Moon.
• The [Jaimini karakas](vedique:karakas-jaimini): your planets ranked by degree, from the Atmakaraka, the soul and what it has come to accomplish, to the Darakaraka, the spouse.

Vedic vs Western astrology: what is the difference?

Both look at the same sky, but not from the same starting point. Western astrology counts the signs from the spring equinox: its zodiac follows the seasons. Vedic astrology counts them from the stars. Because the equinox slowly slides back against the stars (precession), the two zodiacs have drifted about 24° apart. A Sun at 10° Taurus in Western astrology sits at around 16° Aries in Vedic astrology: for most people, the Sun sign moves back by one.

The difference in spirit matters even more. The modern Western chart is first of all a portrait: your character, your needs, the way you love. Jyotish is a reading of path and time: it asks what the soul has come to mature, karma and dharma (right duty, the path that belongs to each person), and above all when things open up, through the dashas. It also gives the Moon the central place that Western astrology often keeps for the Sun.

Neither cancels the other. Western astrology tells you who you are and how you live things; Vedic astrology tells you what is at stake and when. That is why the site keeps the Western chart as the default and adds the Vedic one, so the two can be read together.

Why the Moon matters so much in Vedic astrology

In India, people readily ask for your Moon sign, the Janma rashi, and your birth nakshatra, the Janma nakshatra, the one the Moon was in. It sets your dashas going: life begins in the period of the planet that rules that nakshatra, already partly used up according to how far the Moon had travelled through it.

An example. A Moon at 15° sidereal Taurus sits in Rohini (from 10° to 23°20′ Taurus), a nakshatra ruled by the Moon and placed under Brahma. Life therefore begins in the Moon mahadasha, which lasts ten years; but the Moon had already covered 5° of the 13°20′ of Rohini, three eighths of it: about six years and three months of that period remained. Then come Mars, seven years, and Rahu, eighteen years.

Your Western Moon sign often moves back one sign in Vedic astrology. Rahu is the North Node of the Moon (your Western North Node has its own page), Ketu the South Node: the site calculates them as mean nodes, with Ketu always exactly opposite Rahu.

What does My Birth Chart offer in Vedic astrology?

On the page of your calculated chart, the wheel offers a choice: Tropical (Western) or Vedic (sidereal). Vedic opens the D1, or Rasi, the root chart, and a list gives the twenty divisional charts, from D1 to D60, including Parashara’s sixteen. With each chart, the wheel, the placements and the line that gives its meaning change. Alongside the D1, you also read:

• for each planet, its sign, degree, house, nakshatra and pada;
• your Vimshottari dashas: the current period, the next ones and their dates;
• the nakshatra of your Moon and that of your Ascendant;
• your Atmakaraka and your Karakamsha, the sign of the Atmakaraka in the D9.

The calculation follows the classical rules: Lahiri ayanamsa (Chitrapaksha), mean nodes, whole-sign houses, Parashara’s divisions. It needs your exact birth time: without it, the Vedic option stays switched off. Look for it on the long-form birth certificate or in hospital records.

Your chart answers you, in Vedic too

“Your chart answers you”, the site’s chat, also reads the Vedic chart. A question about your life path or your karma draws on the D60 and the D9, a question about love on the D9 (and the D7 for children), a career question on the D10, money on the D2, spiritual life on the D20, studies on the D24. The answer says clearly when it is speaking in Vedic terms.

This way of working has a name on the site: crossing the charts. No chart is read alone: the answer comes from what several charts say together. You can ask your question as soon as your chart is calculated.

Where to start with Vedic astrology?

Vedic astrology is discovered in layers. Here is the order that makes the most sense:

1. Calculate your birth chart with the exact time, then choose Vedic on the wheel.
2. Read the D1: the sign of the Ascendant, the sign of the Moon, and the nakshatra of the Moon.
3. Find your current dasha: it tells you which planet holds the time right now.
4. Open the D9, the most important chart after the D1, then the divisional chart for the area of life on your mind.
5. Go back to the tropical wheel to compare: where the two charts agree, the reading is solid.
