Durudhura Yoga: the Moon flanked on both sides, the rule as coded, and a worked chart

Durudhura is the both-sides case of the lunar yogas. Where Sunapha needs a planet in the sign after the Moon and Anapha a planet in the sign before it, Durudhura needs both at once - the Moon held between two neighbours. BPHS spells it Duradhar. This page sets out the rule as this app tests it, the texts' readings including Saravali's ten pair-by-pair lines, how often it fires and why it is the rarest of its family, and a chart the engine found. For what any yoga is worth in general, read what a yoga in your chart means.

The rule: how Durudhura Yoga forms

Count from the Moon's sign as the 1st - the Chandra Lagna - by whole signs. The engine reports Durudhura when both of these hold:

1. 1.At least one of Mars, Mercury, Jupiter, Venus or Saturn occupies the 2nd sign from the Moon.
2. 2.At least one of the same five occupies the 12th sign from the Moon.

Because a planet can only be in one sign, these are always two different planets. The Sun does not count on either side - both texts exclude it - and neither do Rahu and Ketu. BPHS says "a Grah other than Surya", which could be read to include the nodes; Saravali, which gives a line for every causing planet and every causing pair, names only the five, and the engine follows that.

The engine tests Durudhura before the other two. If both sides are occupied, it reports Durudhura and stops: the chart is not also given Sunapha or Anapha. That follows Saravali Ch. 13 Sl. 1, which defines the three as the 2nd-only, 12th-only and both cases. And because a Durudhura chart has the Moon's neighbours occupied, it can never be a Kemadruma chart, whose first condition is that both neighbours are empty.

Planets in the Moon's own sign

A planet sharing the Moon's sign is the 1st from it. It is not a neighbour, so it contributes nothing to Durudhura, Sunapha or Anapha. It does matter elsewhere in the same function, though. The engine's Kemadruma test - run only when none of the three lunar yogas has formed - looks for any of the five planets in a kendra from the Moon, and the 1st is a kendra. So a planet conjunct the Moon cannot create Durudhura, but it does keep the chart out of Kemadruma. Degrees, likewise, play no part: a planet at the very end of the 12th sign and a Moon at the very start of its own sign may be only a degree or two apart, and they count exactly as a planet thirty degrees away would.

What the classical texts say

Saravali Ch. 13 Sl. 6 reads the Durudhura native as famous for speech, wisdom, valour and virtue, enjoying freedom, comforts, wealth and conveyances, liberal and well-behaved - and then adds a sting: he "will come to grief by maintaining his family members". BPHS Ch. 37 Sl. 7-10 gives pleasures, charity, wealth, conveyances and an excellent serving force, with no sting. The two agree on comfort and generosity. The engine's line keeps the comfort and turns Saravali's family burden into its other face: "Classically read as bringing freedom, comfort and material ease, alongside real generosity toward family." That is a reframing, and this page names it as one.

Saravali's ten pairs

Saravali Sl. 20-29 goes further than any other lunar-yoga passage in the library: it gives a reading for each pair of causing planets, one on each side of the Moon. There are ten pairs of five planets, and the text covers all ten. Sl. 3 counts 180 kinds of Durudhura in all by permutation, without showing the count. A short summary of the pair lines, as the text gives them:

The engine names the causing planets on each side but does not choose among these ten lines; it shows one line for the yoga. The table is here so that a reader who wants the text's finer reading can find it, and so that it is clear how much the text varies the reading by pair.

How rare it is

Durudhura fired in 314 of 3,000 sampled birth moments 1985-2060 - 10.5 percent, about one chart in ten. Its one-sided siblings were each more than twice as common in the same sample: Sunapha 674, Anapha 682. The friendless-Moon case, Kemadruma, fired 29 times.

The reason is the Moon's lack of companions. The Sun's two-sided case, Ubhayachari, fired 1,020 times in the same sample, because Mercury and Venus stay close to the Sun and often sit on either side of it. Nothing keeps planets close to the Moon. For Durudhura, two of the five must happen to fall in the two signs bordering wherever the Moon is that day.

Unlike the solar yogas, no planet dominates: the five share the work fairly evenly, as you would expect when the Moon's position is unrelated to any of them. In 74 of the 314 moments every causing planet was a benefic (Mercury, Jupiter or Venus) and in 20 every one was Mars or Saturn; the rest were mixed. BPHS gives no benefic-malefic rule for the lunar yogas, so those figures matter only to a reader using Saravali's pair lines.

Worked example: a 1985 New Delhi chart

The engine's search found this chart: 19 January 1985 at 11:14 IST in New Delhi, which you can re-enter in the birth chart calculator. The ascendant is Pisces at 23.04 degrees.

1. 1.The Moon is in Sagittarius. Its 2nd sign is Capricorn and its 12th is Scorpio.
2. 2.Capricorn holds the Sun and Jupiter. The Sun does not count; Jupiter does. Condition one holds.
3. 3.Scorpio holds Saturn and Ketu. Ketu does not count; Saturn does. Condition two holds.
4. 4.Both sides are occupied, so the yoga is Durudhura, and the engine reports neither Sunapha nor Anapha.

The engine reports Durudhura Yoga with the planets Jupiter, Saturn and the Moon and the sentence "The 2nd sign from your Moon holds Jupiter, and the 12th holds Saturn - flanking the Moon on both sides." By Saravali's table this is the Jupiter and Saturn pair, Sl. 28.

This chart is a good test of both exclusions. Each side of the Moon holds one excluded body - the Sun on one side, Ketu on the other. Had the engine counted them it would have changed nothing, since Jupiter and Saturn are already there. But take Jupiter and Saturn away and the picture flips: the Sun alone in the 2nd and Ketu alone in the 12th would give no lunar yoga at all. Note also that Jupiter is debilitated and combust in Capricorn. The Durudhura rule does not test either, so the yoga stands - but this is exactly the weak causing planet that Saravali Sl. 8-9 asks the reader to weigh.

The same chart has Ubhayachari as well: the Sun in Capricorn has Mars and Venus in the 2nd from it and Mercury in the 12th. So both luminaries are flanked here. The engine also returns Kedara, Amala, Argala Raj, Sarala, the Kendra-Kona Raj Yoga and a Parivartana for this chart - eight separate rules met, which says more about how many rules there are than about the chart.

Durudhura beside its neighbouring yogas

Durudhura completes a family of four Moon-based outcomes: Sunapha, Anapha, Durudhura and Kemadruma. The Sun has its own parallel set, Vesi, Vasi and Ubhayachari. Two other Moon-based rules count different houses: Adhi Yoga (benefics in the 6th, 7th and 8th from the Moon) and Gaj Kesari (Jupiter in a kendra from it). In the example, Jupiter is 2nd from the Moon, so it forms Durudhura but not Gaj Kesari.

What the rule does and does not establish

Durudhura establishes that the Moon has one of five planets on each side by sign. The texts read it as comfort and generosity, Saravali with a note about family burdens and ten pair-specific variants, and both ask - Saravali explicitly - that the Moon's state and the planets' strength be weighed. Neither gives a timing rule. A yoga is a named rule about positions, not a promise. Seeing it in your chart tells you exactly that, and not having it takes away nothing the texts guarantee elsewhere.

To check whether your chart has Durudhura, Sunapha or Anapha, and which planets stand on each side of your Moon, run the yoga calculator.

Questions about Durudhura Yoga

What is Durudhura Yoga?

The Moon flanked by planets: at least one of Mars, Mercury, Jupiter, Venus or Saturn in the 2nd sign from the Moon, and at least one in the 12th.

Is Durudhura the same as Duradhar Yoga?

Yes. BPHS Ch. 37 spells it Duradhar; Saravali Ch. 13 spells it Durudhura. The rule is the same.

Does the Sun next to the Moon count?

No. Both texts exclude the Sun from the lunar yogas, and the engine also excludes Rahu and Ketu, following Saravali's list of causing planets.

Can a chart have Durudhura and Sunapha together?

Not in this app. The engine reports one of the three per chart, following Saravali's three-case definition.

How common is Durudhura Yoga?

It fired in 314 of 3,000 sampled birth moments 1985-2060 - 10.5 percent, less than half as often as Sunapha or Anapha in the same sample.

Does it matter which two planets form it?

To Saravali, yes: Sl. 20-29 gives a different reading for each of the ten pairs. The engine names the planets but shows one line for the yoga.

Does a planet in the same sign as the Moon help form Durudhura?

No. A planet with the Moon is the 1st from it, not a neighbour. It does, however, keep the chart out of Kemadruma, because the 1st counts as a kendra from the Moon in the engine's Kemadruma test.

Why is Durudhura rarer than Ubhayachari, its solar counterpart?

Mercury and Venus stay close to the Sun and often flank it; nothing stays close to the Moon. In the same sample Ubhayachari fired 1,020 times and Durudhura 314.

Should I do anything if my chart has Durudhura?

No. It is a named rule about positions. This app does not prescribe remedies.
