How to read a South Indian Rashi chart, house by house
The South Indian chart looks like a puzzle until you know one thing: the twelve boxes never move. The signs are painted on permanently, and it is the first house that shifts from chart to chart. Once you can find it, the other eleven follow in seconds.
The grid never changes
A South Indian Rāśi chart is a 4×4 square with the middle four cells hollowed out, leaving twelve boxes around the edge. Each box is a fixed zodiac sign, always in the same place: Meṣa (Aries) sits second from the left on the top row, and the signs run clockwise from there — Vṛṣabha, Mithuna, Karka down the right side, and so on round to Mīna, which sits immediately left of Meṣa.
This is the opposite of the North Indian diamond chart, where the houses are fixed and the signs move. Both carry the same information. The South Indian form simply asks you to remember one extra step: the chart alone does not tell you where the reading starts.
Find the Lagna first
The Lagna — the ascendant — is the sign that was rising on the eastern horizon at the moment and place of birth. On a printed chart it is usually marked "La", "Lagna" or "Asc", sometimes with a diagonal line across the corner of the box.
That box is the first house. Not Meṣa, not the Moon's sign, not wherever the Sun happens to be: the Lagna box. Everything else is counted from there, clockwise, one box per house.
Counting the twelve houses
Start at the Lagna and count clockwise. If the Lagna is Karka (Cancer), then Karka is the 1st house, Siṁha the 2nd, Kanyā the 3rd, and so on until Mithuna lands as the 12th.
Each house, or bhāva, covers a cluster of subjects. The classical list is remarkably stable across texts:
| House | Classically covers |
|---|---|
| 1st | The body, temperament, general vitality and how you come across |
| 2nd | Wealth held, family of origin, speech, food |
| 3rd | Siblings, courage, effort, short journeys, communication |
| 4th | Mother, home, land and vehicles, peace of mind, schooling |
| 5th | Children, intelligence, past merit, speculation, devotion |
| 6th | Illness, debt, enemies, daily work and service |
| 7th | Marriage and partnership, business partners, open dealings |
| 8th | Longevity, inheritance, sudden change, hidden matters |
| 9th | Father, fortune, teachers, long journeys, principles |
| 10th | Profession, standing, action in the world |
| 11th | Gains, income, elder siblings, networks |
| 12th | Expenditure, foreign places, seclusion, sleep, release |
Four of these — the 1st, 4th, 7th and 10th — are the kendras or angles, traditionally the strongest positions a planet can occupy. The 1st, 5th and 9th are the trikonas, held to be the most benefic. The 6th, 8th and 12th are the dusthānas, the difficult houses, though a planet there is not automatically bad news; several yogas depend on exactly that placement.
Reading what sits in a house
With the houses numbered, a placement reads as a sentence with three parts: which planet, in whose house, and in which sign. Saturn in the 10th house in Libra is a different statement from Saturn in the 10th house in Aries, because Saturn is exalted in Libra and debilitated in Aries.
A practical order of reading:
- Start with the Lagna and its lord. Which sign rises, and where has its ruling planet gone? That pair sets the tone of the whole chart.
- Then the Moon. Its sign is your rāśi in everyday speech, and most transit and daśā reading is measured from it rather than from the Lagna.
- Then the occupied houses. A house with two or three planets in it is being emphasised; an empty house is read through its lord instead, wherever that lord sits.
- Then the aspects. Every planet aspects the 7th house from itself. Mars additionally aspects the 4th and 8th, Jupiter the 5th and 9th, Saturn the 3rd and 10th.
A worked example
Take the sample chart used across this site — 15 May 1990, 10:30, Thiruvananthapuram. It gives Karka Lagna at 2°11′, with the Moon in Dhanu.
So Karka is the 1st house. Count clockwise: Siṁha 2nd, Kanyā 3rd, Tulā 4th, Vṛścika 5th, Dhanu 6th. The Moon therefore sits in the 6th house from the Lagna — a placement classically read as working through service, routine and problem-solving rather than ease.
But notice what happens if you measure from the Moon instead, as transit reading does: Dhanu becomes the first house, and the Lagna sign Karka falls in the 8th from the Moon. The same chart, two frames, two different emphases. Both are used, and confusing them is one of the commonest errors in amateur reading.
What the Navāṁśa adds
Alongside the Rāśi chart you will almost always see a second square: the Navāṁśa, or D9. It divides each sign into nine parts of 3°20′ and maps each part onto a sign of its own, so a planet sitting late in a sign lands somewhere quite different in the Navāṁśa from one sitting early.
It is read as a check on the main chart, traditionally for marriage and for the inner strength of a planet. A planet that looks weak in the Rāśi chart but occupies a good sign in the Navāṁśa is said to be vargottama-supported — and the reverse warns you not to over-read a placement that looks flattering at first glance.
Four mistakes worth avoiding
- Reading the Sun sign. The sign the Sun occupies is what Western horoscope columns use. Indian reading starts from the Moon and the Lagna; your Sun sign will often not even match your rāśi.
- Counting anticlockwise. In the South Indian chart the count runs clockwise. Going the other way gives you a mirror-image chart that will be wrong in every house but the first.
- Reading one placement in isolation. No single position decides anything. A difficult placement aspected by Jupiter, or whose lord is well placed, reads very differently from the same placement standing alone.
- Trusting a rounded birth time. "About 10 o'clock" is not a birth time. If the recorded time is uncertain, be sceptical of every house-based conclusion and lean on the Moon and Nakshatra instead.
Where to go next
Once the houses make sense, the natural next steps are the Vimśottari Daśā, which says which planet's period you are living through, and Gochara, which says where the planets are transiting today relative to your Moon. Together those two answer the question a static chart cannot: when.
