Does Budhaditya yoga make someone intelligent?

The classical reading associates it with intelligence and skill in speech and analysis. Given how common the combination is, it is better read as a tendency in how the mind works than as a statement about ability relative to other people.

What if Mercury is combust in Budhaditya yoga?

Both are true at once and both should be stated: the combination is formed, and Mercury is weakened by closeness to the Sun. Many readings mention only whichever of the two suits the conclusion they want.

Which house is best for Budhaditya yoga?

The texts do not rank houses for it. In practice it is read in the house the pair occupies for your ascendant — in the 10th it speaks to work, in the 5th to learning and expression, and so on.

Budhaditya Yoga: Sun and Mercury together

What is Budhaditya yoga and what does the Sun with Mercury mean?

Budhaditya yoga forms when the Sun and Mercury occupy the same sign. It is read for intelligence, communication and work that uses the mind. It is very common, because Mercury never travels more than 28° from the Sun and therefore shares its sign for a large part of the year — so its presence alone says little without the rest of the chart.

Why this yoga is so common

Mercury orbits closer to the Sun than Earth does, so from here it never appears more than about 28 degrees away. A zodiac sign is 30 degrees wide. The two therefore share a sign for a large part of every year, and Budhaditya is present in a very large share of charts — far more than most pages on the subject admit.

That does not make it meaningless. It makes it a baseline rather than a distinction: the useful questions are which house the pair falls in for your ascendant, which houses Mercury rules there, and whether Mercury is combust.

The combustion question

The same closeness that creates the yoga also creates combustion. When Mercury is within a few degrees of the Sun it is said to be burnt, and classical opinion treats a combust planet as weakened in its ability to give its own results.

So Budhaditya carries a tension inside it: the closer the conjunction, the more exactly the yoga is formed and the more combust Mercury becomes. A reading that reports the yoga without reporting the combustion has told you half of what the chart says. Our engine computes both and reports both.
