Grahas

Graha (graha) is a planet of Indian astrology; there are nine of them in all. When people say the day is colored by Saturn, or that the Moon is passing through a difficult stretch, they mean the grahas: these are the sky's "cast of characters," and it is through their positions that jyotish reads the quality of time. The word literally means "seizing," "grasping" — a graha, as it were, seizes the moment's attention and gives it its own coloring.

This section is an overview. It explains what grahas are in general, how the nine differ from one another, and how they mark out the quality of time; the breakdown of each planet is on its own page.

What makes up the nine

The nine grahas are not nine planets in the astronomical sense. The set includes two luminaries, five "true" planets, and two computed points on the Moon's orbit:

• two luminaries — the Sun and the Moon;
• five "true" planets — Mars, Mercury, Jupiter, Venus and Saturn;
• two shadow points — Rahu and Ketu, the nodes of the lunar orbit, where the paths of the Sun and Moon cross.

Rahu and Ketu have no body — they are mathematical points, not luminous objects, which is why they are called shadow grahas. Classical jyotish counting has no place for the outer planets — Uranus, Neptune, Pluto: the system rests on what is visible to the eye, plus the two nodes. Hence the round number — nine, navagraha.

How the grahas differ

Each graha has its own circle of meanings — an area of life and a type of force it brings to the day. The Sun governs will and authority, the Moon the mind and feelings, Mars energy and action, Mercury speech and calculation, Jupiter growth and knowledge, Venus love and comfort, Saturn discipline and limits. Rahu pulls toward craving and obsession, Ketu toward detachment and closure. These meanings are the anchor on which every reading is built.

Tradition divides the grahas into benefic and malefic by nature. Jupiter, Venus, a waxing Moon and Mercury are counted among the gentle ones; the Sun, Mars, Saturn, Rahu and Ketu among the harsh ones. This division is not about "good" and "bad": a harsh graha does not bring misfortune so much as it sets an obstacle or demands effort, and there is use in that too. The Moon and Mercury are treated as conditional: their nature depends on their surroundings — a waxing Moon is benefic, a waning one loses strength (sources differ on exactly where to draw this line), and Mercury takes on the quality of whichever graha stands beside it. This is the division by a planet's nature; in any one person's chart, the same graha can work differently, depending on which houses it rules from that person's lagna.

States of a graha

A graha's strength depends not only on its nature but on the rashi sign it stands in. The same Mars acts differently in different signs. For this, tradition distinguishes several reference states.

In its sign of exaltation, a graha unfolds most fully and gives its best results. In the opposite sign, its debilitation, its qualities are distorted and weakened. In its own sign, swakshetra, a graha is stable and confident, like a master in his own house. Between these extremes lies a scale of dignity by which an astrologer judges how strong a planet is and what it is capable of.

Seven grahas (all but the shadow points Rahu and Ketu) own zodiac signs — each is responsible for one or two rashis. It is this rulership that connects the grahas to signs, houses and time: through it a planet "reaches" into areas of life.

Grahas and time

Grahas mark out not only the space of the chart but the flow of time. The seven visible grahas rule the days of the week in turn — hence the very names of the days in the panchanga: each day's vara belongs to its own planet. The same seven grahas also rule the hora — the planetary hour of the day, which changes ruler roughly every hour.

Over longer stretches of life, the planetary periods, dasha, are at work: under the Vimshottari system, each of the nine grahas is given its own span of years, during which it sets the underlying tone of a life. And in the unfavorable windows of a day, the shadow grahas surface — Rahu Kala is named after Rahu for exactly this reason. So the same nine planets are read in the day of the week, in the hour, and in the decades-long period alike.

How to read this section

Each graha's article gathers the essentials: which areas of life it governs, whether it is benefic or malefic by nature, which signs it owns, where it exalts and where it falls, and how it shows up as the quality of a day. We deliberately leave theology and mythology aside — this section is practical, meant for a reader who needs to understand the quality of the day rather than go deep into the shastras. A planet's symbol or image can be mentioned, but stories about the deities are not part of it.

A convenient reading order is this: start with this overview to see the whole nine and the logic of benefic and malefic grahas; then open the planet that governs your day — Saturn, say, on a day with a difficult yoga, or the Moon in its nakshatra. Grahas are the level everything else in jyotish rests on: the lunar mansions, nakshatras, are ruled by grahas, and classes of days and periods are counted from them too. Once the nine are sorted out, everything else becomes easier to read.
