Buddha-Aditya Yoga
Buddha-Aditya yoga is the conjunction of the Sun with Mercury. The person will be intelligent, capable, taciturn and respected in society.
Sri Govind Swarup Agarwal — «Vedic Astrology»
Budha-Aditya yoga is formed when Mercury and the Sun are in one house. Aditya is one of the names of Surya. Budha is Mercury. In fact this is combustion. But Mercury and the Sun are friends, and therefore the negative effect of combustion is in a number of cases neutralised. Besides, Mercury is the closest of all to the Sun, and for it combustion is habitual. Budha-Aditya yoga points to intellect, to highly educated people. It shows a good capacity for communication and for the transmission of information, and a person’s abilities in the various sciences, astrology among them. This yoga is met with very often (Mercury never moves further than 28º from the Sun in the Zodiac), and therefore, in order to understand how exactly it will manifest in life (as a weakened Mercury or as a Budha-Aditya yoga), one must analyse the house in which this conjunction occurs, and the chart as a whole.
B.V. Raman notes that Buddha-Aditya yoga shows its strength when Mercury is at a distance of no less than 10º from the Sun.
A Graha in conjunction with the Sun becomes especially significant and accentuated in the life of the native. The Sun is the karaka of energy, of life, of prana, of health and of the Ego, and therefore the Bhava in which the sambandha (conjunction) of the Sun with some Graha occurs becomes important and vividly manifested. Attention should also be paid to the Bhavas ruled by the Grahas taking part in the Yoga. Mercury is the karaka of intellect, of analytical abilities, of the exact sciences, of concentration and of memory. Indeed, the conjunction of the Sun and Mercury is met with very often in birth charts, but not all of its owners have an outstanding intellect, a good memory, or a love of and ability for the exact sciences.
Budha-Aditya yoga accentuates, first of all, the native’s intellect, and not always in a positive aspect. This depends on the position of the Sun and/or Mercury in the signs and, accordingly, in the Bhavas. If both Grahas feel well, then all the positive aspects of Budha-Aditya yoga are manifested; and conversely, if the Grahas (or one of them) feel bad, then serious problems may appear with the intellect, with memory, with the ability to analyse, to build cause-and-effect connections, and to concentrate. One should also take into account the closeness of Mercury to the Sun and the presence of the combustion of Budha. When Mercury is placed within two degrees or less of the Sun, this conjunction takes on an extremely negative character; all the indications of Mercury as a karaka suffer, namely: intellect, memory, calculation, the nervous system, the psyche, the skin, the intestines; the person cannot concentrate, and the native may develop illnesses connected with the loss of intellect. If Mercury is combust (kopa) but does not fall within the range of two degrees from the Sun, then the native, while having good intellectual gifts, may be aggressive, quarrelsome and given to scandal. For example, in defending his scientific views he publicly insults his opponent and may even resort to physical force.
If Mercury is ahead of the Sun in degrees, then the person is more inclined to subjective thinking.
It should be borne in mind that in the Kali Yuga the Sun (a Krura Graha) is also a Papa Graha, and therefore the conjunction of Mercury and the Sun will manifest, besides the positive, certain negative points. To a greater degree if the Grahas (one or both) feel bad, and to a lesser degree if they are in a good position. First, in one way or another the native will show some problems with the state, with authority. Second, this conjunction produces instability in the native’s material position, except when the Budha-Aditya yoga is in the fourth Bhava.
In the Lagna, when well placed, Budha-Aditya yoga testifies to longevity.

Budha-Aditya Yoga
(from «THREE HUNDRED IMPORTANT COMBINATIONS» by B.V. Raman)
Definition.—If Mercury combines with the Sun, the combination goes under the name of Budha-Aditya Yoga.
Results.—Highly intelligent, skilful in all works, good reputation, personal respect and surrounded by all comforts and happiness.
Remarks.—Generally, any planet in association with the Sun becomes combust or Astha and loses its power to do good, perhaps Mercury is an exception. It should not be taken for granted that irrespective of the distance between the Sun and Mercury, Budha-Aditya Yoga would be present. On the contrary, Mercury should not be within 10° of the Sun to give rise to Budha-Aditya Yoga. This combination is not, of course, rare.
We continue our study of the conjunctions of two planets in a person’s horoscope. Today we shall consider the placement of the Sun and Mercury in one house. This yoga is known as Buddha-Aditya yoga. It endows a person with a strong mind, beautiful speech, high qualification in his work, excellent logic and so on. All would be well, but this yoga can be found in half of humanity. Why does it not give its results? How should yogas in a horoscope be analysed correctly?
