Budhaditya Yoga
Budhaditya Yoga places Sun and Mercury in the same sign, recorded as Surya-Buddh Yoga in the catalogue. Traditionally linked with learning and skill, this formation alone does not assess Mercury's complete condition.

How Budhaditya Yoga forms
The Sun and Mercury must occupy the same whole-sign house, meaning the same zodiac sign in this engine. The base formulation does not require a particular ascendant or angular house.
Budhaditya and Budha-Aditya are aliases attached to this specific matched formulation in the extended catalogue. Combustion, closeness and strength may matter to a fuller interpretation, but they are not additional formation requirements in this rule.
Virgo rises in the example, with both the Sun and Mercury in Virgo. The charts show the conjunction in the first house. The first-house placement makes the example easy to read; it is not a requirement of the yoga.

Learning and practical skill
The source describes intelligence, learning and skill in one's work. These are the principal educational and practical themes associated with the combination.
The same text recognises that it is a common yoga. Its presence does not distinguish an inevitable genius or establish a particular level of achievement.

Speech and reputation
Pleasant speech and a good reputation are also included in the traditional description, alongside material resources. They form part of a broad historical portrait.
A useful reading separates the existence of the Sun–Mercury conjunction from how strongly it may be expressed. The name alone is not a ranking of a person's abilities.
Traditional interpretations are not guaranteed outcomes; consider the whole birth chart.
