The Sarvatobhadra Chakra is the great 81-cell transit diagram of Vedic astrology: all 28 nakshatras, the 16 svaras, your name's akshara, the 12 rashis, the tithis and the weekdays woven into one grid. When a transiting graha "pierces" a cell connected to you — a vedha — that day carries its signature. This calculator draws the full chakra live for today and checks your points — nakshatra vedha, naam vedha and rashi vedha — under both classical vedha schools.

What is the Sarvatobhadra Chakra?
Sarvatobhadra means "auspicious from all sides". The chakra is an 81-cell square described in the medieval swarodaya tradition (the Narapatijayacharya names an ekāśīti-pada chakra — the 81-cell wheel) and carried into the classical commentaries on Phaladeepika chapter XXVI. It is not a birth chart: it is a transit instrument, read fresh for each day or muhurta.
What makes it unique is its reach. Alongside the 28 nakshatras it holds the 16 svaras (vowels), 20 name-consonants, the 12 rashis, the five tithi groups and the weekdays — so a single transiting graha can touch your nakshatra, your name, your rashi, your tithi and your weekday at once. That multi-point reading is exactly what the classical verses describe.
How the 9×9 chakra is built
The construction follows fixed rules — every printed chakra that follows the classical verses agrees cell for cell:
- 28 nakshatras around the border, seven per side, starting with Krittika on the east side and running clockwise — with Abhijit given its own cell between Uttara Ashadha and Shravana.
- 16 svaras (अ to अः) on the two diagonals, four per arm, dealt clockwise from the north-east corner.
- 20 name-consonant cells (अ व क ह ड · म ट प र त · न य भ ज ख · ग स द च ल) on the inner 7×7 ring — the avakahada scheme.
- 12 rashis three per side, Taurus starting east, ending with Aries.
- The five tithi groups — Nanda, Bhadra, Jaya, Rikta and Purna in the centre — with the weekdays paired to them.
What is vedha in astrology? Front, left and right
Vedha means piercing. A graha standing in a border nakshatra sends up to three lines through the grid: straight across (front), diagonally in the zodiacal direction (left/fore) and diagonally against it (right/hind). The diagonal lines strike every cell they pass through — svaras, consonants, rashis, tithi cells — which is precisely how a planet ends up piercing your name letter or your rashi. The front line, in the classical reading, strikes only the nakshatra at its far end.
Classically the count of pierced points grades the day: one point pierced brings friction, several together call for real caution — which is why the chakra is first a muhurta tool. This calculator shows the pierced cells on the grid and lists them below it.
The two vedha schools — with sources
The classical manuals differ on how many directions a graha pierces at once — the difference traces to one verse (Horāratna 14) read two ways. We compute both readings and label each by its source; neither is "the correct one".
Classical single-vedha
One operative direction per graha, by motion: retrograde pierces to the right, swift to the left, mean motion straight across; Sun and Moon always left, Rahu and Ketu always right. Source: Horāratna/Rājavijaya verses preserved in the note to Phaladeepika XXVI.48 (Sastri edition).
All-three vedhas
Every graha pierces along all three lines at once — the method documented by P.V.R. Narasimha Rao (Vedic Astrology: An Integrated Approach §26.8) and implemented in Jagannatha Hora.
Predominance
All three lines exist; the graha's motion decides which predominates — the Sanjay Rath / SJC teaching tradition. Luminaries never pierce backward; the nodes never pierce forward.
Shubha and ashubha vedha
The vedha carries the nature of the graha casting it. Saturn, Sun, Mars, Rahu and Ketu count as krura (harsh); Jupiter and Venus as saumya (benefic); Mercury turns harsh only when joined with a harsh graha. The Moon switches with its phase — the manuals give a precise boundary: malefic from Krishna Ekadashi through Shukla Chaturthi, benefic from Shukla Panchami through Krishna Dashami.
Motion and dignity scale the effect: the classical verse assigns a retrograde graha double strength, an exalted one triple, and a debilitated one half. A benefic vedha on your points is a good sign — vedha is not automatically bad.

What is the Sarvatobhadra Chakra used for?
It is a classical transit and muhurta instrument: a fixed 81-cell grid holding the 28 nakshatras, 16 svaras, 20 name-consonants, 12 rashis, tithis and weekdays. Transiting grahas cast vedha (piercing lines) across it; checking whether those lines touch your janma nakshatra, name akshara, rashi, tithi or weekday grades the day or muhurta.
What does vedha mean in the Sarvatobhadra Chakra?
Vedha means piercing. A graha in a border nakshatra sends lines through the grid — straight across, and diagonally to the left and right. The diagonals strike every cell they cross; the front line, classically, strikes only the nakshatra opposite. A pierced cell connected to you carries that graha's influence for the period.
Why does this calculator show two vedha schools?
The manuals genuinely differ. One classical reading (Horāratna/Rājavijaya, preserved in the Phaladeepika XXVI.48 commentary) gives each graha one operative direction based on its motion; the method documented by P.V.R. Narasimha Rao applies all three directions for every graha. Both are published practice, so we compute both and name the sources — rather than silently picking one.
Is vedha always bad?
No. The vedha carries the nature of the graha casting it: Jupiter or Venus piercing your points is a supportive signal, while Saturn, Mars, Sun, Rahu or Ketu call for care. The Moon switches with its phase, and Mercury follows its company. Even harsh vedha is a timing caution, not a fixed outcome.
Which nakshatra scheme does the chakra use — 27 or 28?
The grid itself is 28-star: Abhijit has its own cell between Uttara Ashadha and Shravana (sidereal 276°40′ to 280°53′20″). Your janma nakshatra, though, is always one of the ordinary 27 — Abhijit matters on the transit side.
What is shubha vedha and ashubha vedha?
Shubha vedha is a piercing cast by a benefic (Jupiter, Venus, well-placed Mercury, or the strong Moon); ashubha vedha comes from Saturn, Sun, Mars, Rahu or Ketu. The classical verse also scales strength: retrograde doubles a graha's effect, exaltation triples it, debilitation halves it.
Can a graha pierce my name or my rashi, not just my nakshatra?
Yes — that is the chakra's specialty. The classical verse lists five targets: nakshatra, name-consonant, svara, tithi and rashi, and a further source adds the birth weekday. The diagonal vedha lines pass over the inner rings where those cells sit, so one transit can touch several of your points at once.
How often does the chakra change?
The Moon moves to a new nakshatra roughly every day, so its vedha shifts daily — that is why the chakra is read fresh each morning in muhurta practice. Slower grahas like Saturn and Jupiter hold their vedha lines on the same cells for weeks or months.
Do you use the Lahiri ayanamsha?
Yes — all positions are sidereal with the Lahiri ayanamsha by default, computed with Swiss Ephemeris precision, the same engine used across PanchangBodh.
Vedha is a classical muhurta consideration, not a verdict on your day. Use it to time what you can, and read harsh combinations as a call for care — never as a fixed outcome.
