Ubhayachari yoga is one of the yogas the kundali calculator names most often, and one of the least explained. It forms when planets other than the Moon occupy both signs on either side of the Sun, the sign just before it and the sign just after it, so that the Sun sits in the middle with company on each flank. The classical texts give it a generous reading, and the calculator’s label tends to make people hope for a great deal. Ubhayachari yoga is real and often useful, but it is also common, and what it actually delivers in a chart depends on which planets form it, how strong the Sun is, and when the dasha brings it to life. This page reads it from the astronomy to two charts from practice.
It has two halves, each a yoga in its own right: Vesi yoga when planets stand only in the sign after the Sun, and Vosi yoga when they stand only in the sign before it. The Moon has a matching set of three, and Durudhara yoga is the Moon’s version of Ubhayachari. The Sun’s own nature, as the planet of the self, authority and the father, is on the Sun page.
Conventions used. Parashari astrology, whole-sign houses, the Lahiri ayanamsa and Vimshottari dasha, the Jagannatha Hora settings. The yoga is counted from the Sun’s sign, with the Moon excluded as the classical texts require; Rahu and Ketu are left out here, though some software counts them. The frequencies quoted come from the Swiss Ephemeris, one chart a day across 1950 to 2010. KP appears once, as a labelled aside.
Your Ubhayachari yoga, read for what it will actually give.
A consultation reads the planets on both sides of your Sun, the Sun's own strength, the houses they rule for your ascendant and the dasha periods ahead, so you know how much this yoga promises in your chart and when it is likely to deliver.

What Ubhayachari yoga is
The rule is simple. Count from the sign the Sun occupies. If at least one planet other than the Moon sits in the sign immediately after it, the second from the Sun, and at least one sits in the sign immediately before it, the twelfth from the Sun, the chart has Ubhayachari yoga. The name means moving on both sides. It belongs to the small family of Surya yogas, the yogas formed around the Sun, and it is judged by sign, not by degree, so a planet at the far end of the neighbouring sign counts as fully as one close to the Sun.
Three details trip people up. The Moon never counts, because it has its own set of yogas counted from its own position. Rahu and Ketu are excluded by most classical authorities, but some software includes them, which is why two programs can disagree about whether a chart has the yoga. And a planet in the same sign as the Sun does not count at all; it forms a conjunction with the Sun instead, and in Mercury’s case the familiar Budhaditya yoga. Anyone checking for Ubhayachari yoga in kundli software should therefore look at the two neighbouring signs, not at the Sun’s own house.
Planets before dawn and after dusk
The yoga has a plain astronomical meaning that the old texts took for granted. A planet in the sign before the Sun lies to the west of it in the sky and rises before the Sun, so it is visible in the morning. A planet in the sign after the Sun lies to the east and sets after the Sun, so it is visible in the evening. Ubhayachari yoga is the configuration in which the Sun has planets waiting on both sides of the day, heralds before dawn and attendants after dusk.
That picture also explains which planets usually form it. Mercury and Venus never stray far from the Sun, so they are the planets most often found in its neighbouring signs. Across sixty years of daily charts, Venus took part in 80 percent of Ubhayachari charts and Mercury in 72 percent, against 44 percent for Mars, 33 percent for Jupiter and 31 percent for Saturn. The single commonest form is Mercury on one side and Venus on the other, which accounts for about a fifth of all cases.
How common Ubhayachari yoga is
Under the classical rule, which leaves out the Moon, Rahu and Ketu, Ubhayachari yoga forms in 34 percent of charts, roughly one in three. Vesi yoga alone, with planets only after the Sun, forms in 27 percent, and Vosi yoga alone in 29 percent. Only about one chart in ten has no planet at all in either sign beside the Sun. Software that also counts Rahu and Ketu finds Ubhayachari in about 43 percent of charts, which is why the calculator’s label may appear on a chart that another program leaves unmarked.
The frequency matters for the reading. A yoga found in a third of all charts cannot mean that a third of people become kings, which is roughly what the most enthusiastic classical verses suggest. So the useful question about any Ubhayachari yoga is not whether it is present but what quality it has: which planets form it, in what dignity, around how strong a Sun, and in which houses of the chart.
What the classical texts promise
Parashara and the later compilers, Kalyana Varma in Saravali and Mantreswara in Phaladeepika among them, describe the Ubhayachari native in broadly the same terms: a person who speaks well, is well built and pleasant in appearance, enjoys wealth and comforts, carries responsibility without strain, is respected by those in authority and, in the fullest versions, becomes the equal of a king. The Vesi and Vosi halves each carry a share of these qualities, and the texts add that benefic planets give the good results in full while malefic planets on the Sun’s flanks turn some of them the other way.
Read in modern terms, the promise is of a well-supported self. The Sun stands for identity, authority and the capacity to lead, and planets on both sides of it describe support that surrounds that identity: advisers, colleagues, skills and resources on which the person can draw from either direction. The king in the verses is a person whose position is steadied by the people and abilities around them. That is a more realistic reading of Ubhayachari yoga effects than a promise of royalty, and it is the one that holds up across a practice.
Which planets form it, and what each adds
Each planet on the Sun’s flanks brings its own character to the yoga. The share figures show how often each one takes part in the charts where Ubhayachari forms.
| Planet | How often it takes part | What it adds beside the Sun |
|---|---|---|
| Venus | 80 percent of Ubhayachari charts | Charm, diplomacy and an eye for presentation; comfort and good relations with those in authority |
| Mercury | 72 percent | Speech, writing, analysis and commercial sense; the capacity to explain and represent |
| Mars | 44 percent | Drive, courage and the ability to act on decisions; can add friction with superiors |
| Jupiter | 33 percent | Counsel, ethics and good judgement; support from teachers and elders |
| Saturn | 31 percent | Discipline and endurance; heavy responsibility, often recognised late |
Because Mercury and Venus dominate, most Ubhayachari charts describe a person whose identity is flanked by communication and charm, which is close to what the classical verses describe. When Jupiter is one of the flanking planets the yoga tends to carry counsel and standing, and when Saturn or Mars is involved it tends to carry weight and effort alongside the reward.
Benefic sides, malefic sides and the mixed form
The texts divide every Surya yoga by the nature of the planets forming it. In Ubhayachari charts, benefics alone on both sides, Mercury, Venus or Jupiter, occur in 36 percent of cases; this is the form closest to the classical promise. Malefics alone on both sides, Mars or Saturn with no benefic among them, are rare, about 2 percent, and describe a person whose position is supported by hard work and pressure from both directions rather than by ease. The remaining six in ten are mixed, with a benefic on one side and a malefic on the other, or both kinds together in one sign.
For the mixed form, which is the usual one, the side matters. Planets in the sign after the Sun are read with the Vesi half of the yoga, and planets in the sign before it with the Vosi half, and each half is discussed in its own article. As a working rule, a benefic on one flank and a malefic on the other gives a person who has both easy support and a demanding one, often a helpful colleague on one side and a hard taskmaster on the other.
The Sun in the middle decides how much it gives
The most important factor in any Ubhayachari yoga is the Sun itself. A strong Sun, exalted in Aries, in its own sign Leo, or in the tenth house where it has directional strength, turns the yoga into a genuinely supported position. A weak Sun, debilitated in Libra without cancellation or placed in a difficult house, can still carry the yoga, but then the support around it tends to matter more than the person’s own authority, and people with this pattern often do best in partnerships or teams where others hold the formal role.
Combustion adds a second layer. Mercury and Venus are the usual flanking planets, and when either sits within its combustion orb in the neighbouring sign, it still counts for the yoga but works under the Sun’s authority rather than beside it. The effect of that is read in combust Mercury and combust Venus. A flanking planet placed well away from the Sun, near the far edge of the neighbouring sign, keeps more of its own voice and usually gives the more independent form of the yoga.
Standing, speech and the people around you
In practice Ubhayachari yoga shows most clearly in how a person’s standing is built and kept. People with a well-formed yoga tend to be surrounded by useful support: a colleague who handles what they are weaker at, a mentor on one side and a capable junior on the other, or their own complementary skills, a gift for words beside a gift for managing people. They are often good representatives, of a family, a firm or an institution, because the flanking planets give them the means to present and defend a position. Where the yoga involves the tenth house or the Sun rules an important house for the ascendant, it frequently shows in career, and the site’s career astrology guide covers how the Sun and the tenth are read together.
The yoga also has a quieter, personal meaning. The Sun is the self, and planets on both sides of it describe a sense of self that is steadied by connection rather than by isolation. Its opposite, for the Moon, is Kemadruma, the Moon with no planets on either side, which the site covers in the guide to Kemadruma yoga. There is no named equivalent for an unflanked Sun, and a chart without Ubhayachari, Vesi or Vosi is simply a chart in which the Sun’s support comes from elsewhere.
When Ubhayachari gives little
Four conditions weaken the yoga in practice. The first is a weak, afflicted Sun, debilitated without cancellation or hemmed in by malefics, since the support around a faltering centre can do only so much. The second is flanking planets in poor condition: debilitated, deeply combust, or defeated in planetary war. The third is lordship, since flanking planets that rule difficult houses for the ascendant bring those houses’ matters into the yoga along with their support. The fourth is placement, because a yoga falling in the sixth, eighth or twelfth houses from the lagna tends to show its results through service, upheaval or private life rather than public standing.
There is also the question of the nodes. Where a program counts Rahu or Ketu, a chart may be labelled Ubhayachari when one flank holds only a node. Most practitioners read such a chart as having Vesi or Vosi rather than the full yoga. KP does not use yogas of this kind at all, and reads the same questions through significators and the sub-lord, as yogas in KP explains.
When the yoga delivers
Like every yoga, Ubhayachari shows its results in the dasha periods of the planets that form it. The Sun’s own six-year Mahadasha, covered in Sun Mahadasha, is the most direct activation, since the Sun is the centre the yoga surrounds. The Mahadashas and sub-periods of the flanking planets come next, especially when a flanking planet rules the tenth, ninth or lagna. A person running the period of Venus or Mercury while those planets flank the Sun often finds that this is when the support around them turns into recognition.
Transits add timing within those periods. Jupiter’s transit over the natal Sun or through either flanking sign commonly marks the year in which a promotion, an appointment or a public role arrives, provided the dasha supports it. A transit alone rarely does anything with the yoga. The dasha opens the door and the transit marks the day.
Two charts with Ubhayachari yoga
A Virgo ascendant woman, particulars altered. The Sun in Gemini in the tenth house, where it has directional strength; Mercury, her lagna and tenth lord, in Taurus in the ninth, the sign before the Sun, ten degrees behind it and combust; Venus, her second and ninth lord, in Cancer in the eleventh, the sign after the Sun. That is a benefic Ubhayachari, Mercury and Venus on the two flanks of a strong Sun. The Moon sits in Scorpio in her third house of communication, late in Jyeshtha, so the last three years of Mercury’s period and Ketu’s seven came first, then Venus’s twenty from ten, and the Sun’s six from thirty. She became a newspaper reporter at twenty-three, in Venus-Saturn, and at twenty-seven, in Venus-Mercury, a series she wrote on public hospitals won a state award. At thirty, as the Sun’s own Mahadasha began, she was appointed official spokesperson for the state health department, a representative’s role built on words and charm around an authoritative centre.
A Libra ascendant man, particulars altered. The Sun debilitated in Libra in the lagna, without cancellation; Mercury, lord of the ninth and twelfth, exalted in Virgo in the twelfth, the sign before the Sun; Mars, lord of the second and seventh, in its own sign Scorpio in the second, the sign after the Sun. That is a mixed Ubhayachari with strong planets on both flanks around a weak Sun. The Moon in Sagittarius in the third, in Purva Ashadha, so twelve years of Venus, then the Sun’s six, the Moon’s ten, and Mars’s seven from twenty-eight. He worked in a transport company through his twenties, where his planning was noticed but his confidence was not. At thirty-one, in Mars-Saturn, Saturn being the yogakaraka for Libra, he co-founded a logistics firm with a partner who handled clients and the public face while he ran planning and operations. At thirty-four, in Mars-Sun, the firm won its first large contract.
The two charts show why the Sun matters as much as the flanks. In the first, a strong Sun let the yoga work as the classical texts describe, with the person herself in the visible role. In the second, a weak Sun meant the yoga worked through a partnership, with the flanking strengths doing the work and someone else holding the formal position.
Frequently asked questions
What is Ubhayachari yoga?
It is the yoga formed by planets on both sides of the Sun: at least one planet other than the Moon in the sign after the Sun and at least one in the sign before it. It is one of the Surya yogas, the yogas counted from the Sun, and it describes a sense of self and a position supported from both directions.
Is Ubhayachari yoga rare?
No. Under the classical rule it forms in about one chart in three, and in about two in five when a program also counts Rahu and Ketu. Is Ubhayachari yoga rare enough to be special on its own? It is not, which is why its quality, the planets forming it and the strength of the Sun, matters more than its presence.
Which planets can form Ubhayachari yoga?
Mercury, Venus, Mars, Jupiter and Saturn. The Moon is excluded by rule, and Rahu and Ketu are excluded by most classical authorities though some software includes them. Venus and Mercury form it most often because they are always close to the Sun.
What is the difference between Vesi, Vosi and Ubhayachari yoga?
Vesi has planets only in the sign after the Sun, Vosi only in the sign before it, and Ubhayachari in both. The three are often listed together as Vesi Vosi Ubhayachari, the Sun’s counterparts to the Moon’s Sunapha, Anapha and Durudhara.
Does a combust Mercury or Venus cancel Ubhayachari yoga?
No. The yoga is judged by sign, so a combust planet in a neighbouring sign still counts. Combustion changes how that planet’s support works, through the Sun’s authority rather than independently, but it does not remove the yoga.
What are the effects of Ubhayachari yoga?
The classical texts describe eloquence, good health and appearance, wealth, and respect from those in authority. In practice the yoga most often shows as a well-supported position: useful people and complementary skills around the person, and a talent for representing a family, a firm or an institution. Its strength depends on the Sun and on the planets forming it.
When does Ubhayachari yoga give results?
In the dasha periods of the Sun and of the planets forming the yoga, especially those ruling important houses for the ascendant. Transits of Jupiter over the Sun or through the flanking signs often mark the specific year, but only when the dasha supports it.
A yoga is a promise; the dasha is the delivery date.
A consultation reads your Ubhayachari yoga by the planets on each side of the Sun, the Sun's own strength and the houses involved, and names the periods in which its support is most likely to turn into recognition.
