Planetary dignity in Vedic astrology: strong and weak planets

Planetary dignity means the strength a planet gains from the sign it occupies. P.V.R. Narasimha Rao (PVR), author of Vedic Astrology: An Integrated Approach, writes that each planet has a sign where it is exalted (uchcha, its strongest placement), a sign where it is debilitated (neecha, its weakest), a moolatrikona sign, and one or two signs it owns.

A planet is read as strong in its own rasi (a sign), its exaltation rasi or its moolatrikona.

The Brihat Parashara Hora Shastra (BPHS, R. Santhanam's translation), a classical Sanskrit text of Jyotish (Vedic astrology), gives the full table in chapter 3, and PVR reproduces it as Table 6. Read it row by row: find a planet, then move across to see its exaltation sign and deepest degree, its debilitation sign, its own signs, and its moolatrikona range.

One pattern helps: a planet is debilitated in the seventh sign from its exaltation sign, directly across the zodiac, and 'the same degrees of deep exaltation apply to deep fall'.

Where one sign holds two dignities, BPHS splits it by degree: the Sun's Leo is moolatrikona for the first 20 degrees and own sign after, the Moon's Taurus is exaltation for the first 3 degrees and moolatrikona after, and Mercury's Virgo is exaltation for 15 degrees, moolatrikona for the next 5 and own sign for the last 10.

So a planet's exact degree within a sign can change its dignity. That is why the table records degrees, not just signs.

All three of own sign, moolatrikona and exaltation are good placements, but 'there is a subtle difference in the mood of the planet', as PVR puts it. His analogy: the own sign is like home, the most natural and comfortable setting; the moolatrikona is like the office, where one is duty-minded; the exaltation sign is like a favourite party or picnic, where one is excited; and the debilitation sign is like the worst party, 'an unhappy person stuck at a place he hates'.

PVR walks through Jupiter as an example. Pisces is Jupiter's home, where it is at ease as itself. Sagittarius, its moolatrikona, is its office, where it upholds dharma (right duty or order) as a duty.

In Cancer, its exaltation sign, Jupiter is excited. In Capricorn, its debilitation sign, it is unhappy doing work against its nature.

The analogy is a memory aid, not a prediction. It describes the traditional mood of a placement in general terms.

Chapter 3 of BPHS gives a ratio of effects. A planet in exaltation gives fully good effects; in moolatrikona, three quarters; in its own sign, half; in a friend's sign, a quarter; in a neutral's sign, one eighth; in debilitation or an enemy's sign, nil.

One line changes how the whole scale reads: 'Inauspicious effects are quite reverse.' The same scale runs the other way for a planet's difficult effects, fullest in debilitation and an enemy's sign, least in exaltation.

Treat the ratios as a teaching device from the tradition rather than a precise measurement. They show that dignity is a matter of degree, not a switch between good and bad.

Natural relationships are fixed between planets, aside from any particular chart. BPHS chapter 3 gives the rule: from a planet's moolatrikona, the lords of the 2nd, 4th, 5th, 8th, 9th and 12th signs, plus the lord of its exaltation sign, are its friends; the rest are enemies; a planet that qualifies both ways is neutral.

PVR's Table 7 lists the results. Read one row to see how it works: for the Sun, the friends are Moon, Mars and Jupiter, Mercury is neutral, and Venus and Saturn are enemies. For the Moon, the enemies column is empty, meaning no planet is the Moon's natural enemy.

A second, chart-specific layer applies. In a given chart, planets in the 2nd, 3rd, 4th, 10th, 11th and 12th signs from a planet are its temporary friends; the others are temporary enemies.

Combining the natural and temporary relationships gives five grades: adhimitra (great friend), mitra (friend), sama (neutral), shatru (enemy) and adhishatru (great enemy). The compound table below shows how the two layers combine. PVR notes that when texts speak of a 'friendly house' or 'inimical house', they mean these compound relationships.

The details differ between texts, and it is worth knowing this before comparing books. B.V. Raman, author of Hindu Predictive Astrology, gives the Moon's moolatrikona as Taurus 4 degrees to 20 degrees, where BPHS and PVR give the rest of Taurus after 3 degrees, and Mercury's as Virgo 16 degrees to 20 degrees.

For Rahu and Ketu (the north and south nodes, two shadow points treated as planets in Jyotish) the disagreement is larger: PVR gives their exaltation signs as Gemini and Sagittarius, while the BPHS dasha chapter (a dasha is a planetary period) and Raman give Taurus and Scorpio.

Dignity is one of several conditions recorded for a planet. Others include retrograde motion (vakra, when a planet appears to move backwards in the sky) and combustion. Raman writes that planets in intimate conjunction with the Sun 'get combustion and become utterly powerless'.

Saravali (by Kalyana Varma) devotes a whole chapter, chapter 45, to the effects of planets in exalted, moolatrikona, own, friendly, inimical and debilitation signs.

This is Skybond's teaching chart, not a real person's, so treat it as a reading exercise. Venus in Pisces is exalted, since Pisces is Venus's exaltation sign in the table above. Saturn in Capricorn is in its own sign, one of the two signs Saturn owns, and no planet in this chart is debilitated.

The remaining rows use natural relationships from Table 7. The Moon in Leo sits in the Sun's sign, a friend to the Moon, so it is in a friend's sign.

Mars in Gemini and Jupiter in Virgo sit in Mercury's signs, an enemy to each, and the Sun in Capricorn sits in Saturn's sign, also an enemy. Mercury in Aquarius sits in Saturn's sign, and Saturn is neutral to Mercury.

Skybond's engine uses the BPHS chapter 3 tables for exaltation (with the deepest degrees), debilitation, own signs and moolatrikona, with its moolatrikona ranges starting the Moon at 4 degrees of Taurus and Mercury at 16 degrees of Virgo, the starting points Raman gives. For Rahu and Ketu it uses exaltation in Taurus and Scorpio and debilitation in Scorpio and Taurus.

Skybond marks each planet's dignity in your chart, and its transit pages show a Dignity column: own, moolatrikona, exalted, debilitated, friend, enemy or neutral. Planned lessons in this module go further into exaltation and debilitation, own sign and moolatrikona, and friendly and enemy signs.

A caution from the tradition itself. Raman notes that such descriptions 'are only general in nature and should not be applied hastily', and OnlineJyotish suggests treating interpretations 'as traditional associations rather than promises'.
