What is Budha-Aditya Yoga?

Budha-Aditya Yoga is the conjunction of Mercury (Budha) and the Sun (Aditya) in the same sign, and therefore the same house, of the rasi chart. No degree condition, no house condition and no dignity condition is part of the definition. The conjunction alone forms it.

Is Budha-Aditya Yoga formed in the same house or the same sign?

Both, in ordinary Indian practice. Vedic charts are normally read with whole-sign houses, where one sign is one house, so a shared sign is automatically a shared house. The two conditions only separate under a cusp-based system such as KP, Sripati or Placidus, where the Sun and Mercury can sit in one sign but fall on either side of a house cusp. Vidhata tests house equality.

Is Budha-Aditya Yoga mentioned in Brihat Parashara Hora Shastra?

Not by that name. The words Budha-Aditya, Budhaditya and Nipuna do not appear anywhere in R. Santhanam’s translation of Brihat Parashara Hora Shastra. The reading is classical, and the effects of the Sun with Mercury in one house are given in Saravali chapter 15 and in Jataka Parijata chapter 8. The label Budha-Aditya is later usage.

How many degrees make Mercury combust?

Fourteen degrees from the Sun when Mercury is in direct motion, and twelve degrees when Mercury is retrograde. Those arcs come from Surya Siddhanta and are reproduced in R. Santhanam’s table of combustion degrees in his notes to Brihat Parashara Hora Shastra chapter 7. Vidhata uses the same two figures.

Does Budha-Aditya Yoga still work if Mercury is combust?

It still exists, because combustion is not part of the definition. Whether it delivers is the harder question. Parashara 7.28-29 grades a planet by its distance from the Sun and says a planet at the same longitude as the Sun destroys the good effects, with a proportional scale in between. Santhanam adds, in his note on the same verses, that yogas formed by closeness to the Sun do not simply fail to fructify. Read a combust Budha-Aditya as an intelligence that works, with recognition that arrives late or through someone else.

How common is Budha-Aditya Yoga?

Common enough that it explains very little on its own. Mercury never moves more than about 28 degrees from the Sun and a sign is 30 degrees wide, so a shared sign is close to a coin flip. The figure of 30 percent that circulates online has no source in the texts or in the ephemeris.

Which house is best for the Sun and Mercury conjunction?

The classical texts give no house-by-house verdict for this pair. Working from the bhava significations, the 10th brings the pair closest to public standing and the 5th and 9th to teaching and counsel. The 6th, 8th and 12th turn the same intelligence inward or into work that is not credited publicly. Dignity of the two planets and the degree gap usually outweigh the house.

Is Budha-Aditya a raja yoga?

No. Raja yogas are formed by a relationship between a kendra lord and a trikona lord. Budha-Aditya is a conjunction yoga between two grahas and belongs to a different family. Saravali’s verse for this pair opens with service and unsteady wealth, which is not raja yoga language.

How is Budha-Aditya different from Bhadra Yoga?

Bhadra is one of the five Pancha Mahapurusha yogas and needs Mercury in Gemini or Virgo and in a kendra from the lagna. The Sun is not involved. Budha-Aditya needs Mercury with the Sun and cares about nothing else. They overlap when Mercury sits in Gemini or Virgo in a kendra with the Sun in the same sign, and that overlap is usually weaker than Bhadra alone, because the Sun is close enough to take the combustion toll.

Does the degree gap between the Sun and Mercury matter?

It is the single most useful number in the reading. Parashara sets a sliding scale from full effect at opposition to destroyed effect at identical longitude, and the combustion arc of 14 degrees sits inside that scale. A Sun and Mercury 22 degrees apart in one sign and a Sun and Mercury one degree apart in one sign form the same yoga on paper and behave nothing alike.
