The Nine Grahas

The nine planetary forces of Vedic astrology — what they govern, the days they rule, and the qualities they bring to a life

In Vedic astrology, a planet is a graha — a Sanskrit word meaning “that which seizes,” “that which holds,” or “that which influences.” Vedic astrology treats the grahas as living cosmic forces, each carrying a distinct personality, a domain of life, an organ of the body, a metal, a gemstone, a color, and a day of the week.

There are nine grahas in the Vedic system: the seven classical planets visible to the naked eye, and the two shadow grahas, Rahu and Ketu, which are mathematical points where the moon’s orbit crosses the apparent path of the sun. Together, these nine weave the entire fabric of a Vedic birth chart.

Why Nine Grahas

Modern Western astrology adds Uranus, Neptune, and Pluto, found by telescope from 1781 on. Vedic astrology keeps the nine, for two reasons:

  1. The nine grahas were defined before the telescope. Each is visible to the naked eye, or in the case of Rahu and Ketu, observable through eclipses.
  2. The Vimshottari Dasha — the central timing method of Jyotisha — divides a 120-year life among these nine, and Parashara gives each its share.

The Vedic tradition built its whole method of interpretation on the original nine.

The Seven Classical Grahas

The body tissue and temperament of each graha follow Parashara, the sage behind Brihat Parashara Hora Shastra, the founding text of Vedic astrology. The gemstones follow a later classic, Vaidyanatha Dikshita’s Jataka Parijata.

1. Surya — The Sun

2. Chandra — The Moon

3. Mangala — Mars

4. Budha — Mercury

5. Guru (Brihaspati) — Jupiter

6. Shukra — Venus

7. Shani — Saturn

The Two Shadow Grahas

Rahu and Ketu are the two points where the moon’s orbit crosses the ecliptic — the two eclipse points. An eclipse happens only when a new or full moon falls near one of these crossings. In the Mahabharata, the demon Rahu slipped among the gods to drink the nectar of immortality. The sun and moon recognized him, and Vishnu cut off his head with his discus before the nectar passed his throat. The head still chases the sun and moon and swallows them at each eclipse. Jyotish names the head Rahu and the body Ketu. Modern astronomy calls them the north node and south node of the moon.

8. Rahu — The North Node

9. Ketu — The South Node

Friends, Enemies, and Neutrals

Parashara describes a web of friendships and enmities among the grahas that affects how the planets behave when they share a sign or a house. In simplified form:

These relationships are read layer by layer as a chart is interpreted.

How the Grahas Govern Time

Each of the nine grahas governs a stretch of life in the Vimshottari Dasha system — the most widely used Vedic timing method. The full cycle is 120 years. The order and length are fixed:

  1. Ketu — 7 years
  2. Shukra — 20 years
  3. Surya — 6 years
  4. Chandra — 10 years
  5. Mangala — 7 years
  6. Rahu — 18 years
  7. Guru — 16 years
  8. Shani — 19 years
  9. Budha — 17 years

Which dasha a person is born into depends on the position of the moon at birth. The dashas unfold in the same fixed sequence, regardless of who you are. This is why knowing your janma nakshatra — the lunar mansion holding the moon at your birth — matters: it tells you which dasha you began with, and therefore the whole arc of timing for the rest of your life.

Remedial Measures (Upayas)

If a graha is poorly placed or weak, the Vedic tradition offers upayas — remedial practices. Five are common:

Where the Grahas Meet a Life

A Vedic birth chart is, at its simplest, a map of where each of the nine grahas was sitting at the moment a person was born. The signs they occupied, the houses they fell into, the aspects they cast across the chart, and the dasha they were preparing to hand off — all of these are read together. A Vedic reading looks at all of them at once to describe a person’s character, their gifts, the timing of major events, and the kind of effort each chapter of life will ask of them.

Knowing the grahas one by one is the beginning of being able to read your own chart. Each graha is a teacher, and each has something to offer.

Where the nine were standing on the day you were born is the part only your own chart can show. A personal Vedic birth chart maps each of them from your date, time, and place of birth.

Meet the grahas one at a time — in the chart of the sky, and the chart of your own life.
