Yuga Yoga: all seven grahas in two signs, the BPHS rule, and how rare it is

Yuga Yoga is what a chart is called when its seven visible grahas crowd into just two signs. It belongs to the Nabhasa yogas, the family that reads the whole chart's distribution rather than any single planet, and within that family to the seven Sankhya ("number") yogas, which do nothing but count. Every chart has exactly one Sankhya yoga, because every chart has some count of occupied signs between one and seven. Two is the second-rarest count of all. This page sets out the rule as Brihat Parashara Hora Shastra and Saravali state it, says exactly how this app tests it, and works through the first chart in the engine's sample that has it. What any yoga is worth in general is the subject of what a yoga in your chart means.

The rule: how Yuga Yoga forms

BPHS Ch. 35 Sl. 16-17 gives all seven Sankhya yogas in one sentence: one sign is Gola, two is Yuga, and so on up to seven. The engine turns that sentence into three steps, and Yuga Yoga is reported when the last step gives 2.

1. 1.Take the seven classical grahas: Sun, Moon, Mars, Mercury, Jupiter, Venus and Saturn. Rahu and Ketu are not counted, because the Nabhasa chapter counts "all the Grahas" of the classical seven and the engine uses that list for every Nabhasa yoga.
2. 2.Note the sidereal sign (rashi) each one occupies.
3. 3.Count how many different signs appear. If the answer is exactly two, the chart has Yuga Yoga.

Three things the rule does not ask are worth stating, because people often assume them. It does not care which two signs, or whether they are next to each other. It does not care how the seven are divided - six in one sign and one in the other counts the same as four and three. And it does not involve the ascendant at all: the count is of signs, so a Yuga chart is Yuga whatever is rising. The birth time matters only because the Moon moves quickly enough to change sign within a day and so change the count.

The precedence clause the engine records but does not apply

The same sloka ends with a condition: none of the seven Sankhya yogas "will be operable, if another Nabhash Yog is derivable". The engine's source comment records that clause and deliberately does not apply it. Every Nabhasa yoga that forms is reported, so a chart can show Yuga Yoga next to another member of the family. If you follow BPHS strictly, you would set the Yuga aside in that case. Saravali Ch. 21 Sl. 7 has a precedence rule too, but it is about the Asraya yogas (Rajju, Musala and Nala), not the Sankhya ones.

For Yuga the clause matters more than it might seem, because several other Nabhasa yogas can only form on a two-sign chart. Gada (all seven in two successive kendras), Shakata (all in the 1st and 7th) and Vihaga (all in the 4th and 10th) each put the seven grahas in exactly two occupied houses, which under whole-sign houses means exactly two signs. Every one of those charts is a Yuga chart as well. And if both of the occupied signs share a modality - both movable, both fixed or both dual - one of the Asraya yogas forms too. Under the BPHS clause, Yuga survives only when none of these is present.

What BPHS and Saravali say about Yuga Yoga

The two texts agree on the rule and differ a little on the name list and the reading.

• BPHS Ch. 35 Sl. 1-2 counts 32 Nabhash yogas, seven of them Sankhya. Sl. 3-6 lists those seven as Vallaki, Daam, Paash, Kedara, Sool, Yuga and Gola, running from the most signs down to the fewest; Sl. 16-17 gives the same seven in the opposite order, ending with Veena for seven signs. Yuga has the same name in every list.
• BPHS Ch. 35 Sl. 48 gives the effect: the person will be a heretic, devoid of wealth, discarded by others, and devoid of sons, mother and virtues.
• Saravali Ch. 21 Sl. 19 states the same counting rule ("in 2 Rasis - Yuga Yoga"), and Sl. 47 gives a closely parallel reading: a religious hypocrite, bereft of wealth, forsaken by people, devoid of sons, honour and virtues. Where BPHS names the mother, Saravali names honour.
• Saravali Ch. 21 Sl. 8-10 adds something BPHS does not: a reading for the Sankhya group as a whole - one who is happy only with others' wealth, lives through others' help and is "always not peaceful".
• BPHS Ch. 35 Sl. 50 closes the chapter by saying the results of these yogas are felt throughout all the dasha periods rather than in any one of them.

Advanced Predictive Astrology and the Bhrigu Sutras, the other two yoga sources in this library, do not name Yuga Yoga or the Sankhya group at all.

How rare Yuga Yoga is

In the engine's deterministic sample - 3,000 birth moments from New Delhi, one every 9 days 2 hours 37 minutes from 1 January 1985 - Yuga Yoga fired 10 times, 0.3 percent. Because exactly one Sankhya yoga applies to every chart, the seven counts share out the whole sample, and Yuga sits at the thin end:

Why so few? Mercury never strays far from the Sun and Venus not much further, so those three are often close together. But Yuga also needs the Moon, Mars, Jupiter and Saturn to fall into the same two signs, and the slow planets only gather like that in occasional seasons. The ten Yuga moments in the sample came in clusters: 4 May 2000, 18 August 2004, 13 May 2011, 11 February 2021, 28 February 2022, 30 May 2032, 20 July 2036, 9 September and 7 October 2040, and 24 February 2058. Run on across the whole 20,000-moment walk, which reaches October 2483, the engine met a two-sign chart 49 times. These are counts of sampled chart moments, not of people.

One of the ten, 11 February 2021, also formed Rajju Yoga: six grahas were in Capricorn and Mars in Aries, and both signs are movable. That is the only one of the ten where the BPHS precedence clause would set Yuga aside.

Worked example: 4 May 2000, New Delhi

The first moment in the engine's walk where Yuga Yoga forms is 4 May 2000 at 07:15 IST in New Delhi. You can re-enter it in the birth chart calculator. The ascendant is Taurus at 16.2 degrees.

The count is quick: six grahas in Aries, one in Taurus, so two signs, and the engine reports "Your 7 classical grahas (Sun through Saturn) occupy exactly 2 distinct signs". Aries is the 12th house from a Taurus ascendant and Taurus the 1st, but that plays no part in the yoga - the same seven positions would be Yuga under any ascendant.

Now test the precedence clause by hand. The two occupied houses are the 12th and the 1st. That is not two successive kendras (no Gada), not the 1st and 7th (no Shakata) and not the 4th and 10th (no Vihaga). Aries is a movable sign and Taurus a fixed one, so no Asraya yoga forms. Two houses cannot fill three kendras, so neither Dala yoga can form. The engine agrees: of the yogas it returns for this chart, Yuga is the only Nabhasa yoga. So this is a Yuga chart that BPHS would let stand.

The same chart carries several other yogas that have nothing to do with the count - among them Sunapha, Mudrika, Harsha and Sarala. That is a useful reminder that the Sankhya count is one lens among many, not a summary of the chart.

Yuga beside its neighbours in the count

The Sankhya yogas form a ladder. One rung below Yuga is Gola Yoga, all seven grahas in a single sign, which the engine did not meet once in 20,000 sampled moments. One rung above is Sula Yoga, three signs, fifteen times as common in the sample. Most charts sit in the middle at Kedara, Pasa or Damini, with Veena (all seven signs different) at the far end. A move of one graha across one sign boundary is enough to step a chart up or down the ladder, which is why the Sankhya yoga of a birth near such a moment depends on the exact time.

What Yuga Yoga does not tell you

Yuga Yoga records one fact: how many signs the seven grahas use. It does not say which houses are strong, which planets are dignified or which Mahadasha will bring what. Because no single graha owns it, this app gives it no dasha window of its own - its timing step says it is "a whole-chart pattern rather than a placement of particular grahas". That happens to match BPHS Ch. 35 Sl. 50, which says Nabhasa results run through every period. The classical reading attached to it is the texts' claim, reported here and reframed by the engine; it is not something this app forecasts for anyone.

To see which Sankhya yoga your own chart has, and any other Nabhasa yoga next to it, run the yoga calculator. It shows the count it found, so you can check it against your planets.

Questions about Yuga Yoga

What is Yuga Yoga in simple terms?

It is the name for a chart in which the Sun, Moon, Mars, Mercury, Jupiter, Venus and Saturn together occupy exactly two signs. It is one of the seven Sankhya (counting) yogas in BPHS Ch. 35 and Saravali Ch. 21.

Do Rahu and Ketu count towards Yuga Yoga?

No. The Nabhasa yogas count the seven classical grahas only, and the engine does the same. In the worked example Rahu is in Cancer and Ketu in Capricorn, and the chart is still Yuga.

Does the ascendant matter for Yuga Yoga?

Not for the count. Yuga depends only on how many signs the seven grahas use. The ascendant decides which houses those signs are, which matters for other Nabhasa yogas such as Gada or Shakata, but not for Yuga itself.

How common is Yuga Yoga?

Rare. It fired in 10 of 3,000 sampled birth moments 1985-2060 (0.3 percent), and 49 times in the engine's full 20,000-moment walk to 2483. Only Gola, with all seven in one sign, is rarer.

Why does BPHS say a Sankhya yoga may not be operable?

BPHS Ch. 35 Sl. 16-17 says none of the seven Sankhya yogas operates if another Nabhasa yoga can be derived. Gada, Shakata and Vihaga always produce a two-sign chart, so a chart with one of them is also Yuga, and BPHS would give precedence to the shape. This app records the clause but reports every yoga that forms.

Is Yuga Yoga bad?

BPHS and Saravali attach a harsh reading to it. This app paraphrases that as a tendency toward inconsistency in follow-through, and treats it as a named rule about positions, not a verdict on a person. Saravali also gives a single reading for all seven Sankhya yogas together, which shows how general these readings are.
