Sun-Rahu Grahan Yoga by House Group
A Sun-Rahu conjunction is Grahan yoga located in one house. Kendras make the eclipse public, on the self, the home, the spouse, or the career. Trikonas pull it into children or into the father-house. Dusthanas pull it into conflict, rupture, or expense. The sign lord still disposits both grahas.
The four kendras are four offices
Grahan in the 1st identifies the person with a struggle about authority. The lagna lord has to be strong if the personality is to steer the node rather than the reverse. In the 4th, the eclipse falls on property and the private life, and the father-karaka is sitting in the mother's house, a crossed pair of karakas worth naming. In the 7th, bosses and partners share a theme: the spouse and the public other are solar and nodal. In the 10th, the eclipse is on the throne itself. Dig bala gives the Sun strength in the 10th, so this is a powerful and complicated career placement, not a weak one. Rahu does not cancel that directional strength. It complicates it.
Trikonas, especially the 9th
The 5th-house version puts the king and the node on intelligence, romance, and children. Authority issues show up as pride in the mind or a fraught creative life. The 9th-house version is the one that deserves the pitra discussion, because the Sun is the father karaka sitting in the father house, with Rahu. Fortune and gurus are part of that same bhava. A 9th-house Grahan with the 9th lord exalted is a wound with resources. A 9th-house Grahan with the 9th lord in the 8th is a wound with rupture. The house number is not the whole sentence.
Dusthanas and the six-year Sun period
In the 6th, solar authority is spent on enemies, debt, and service, sometimes as a person who fights institutions. In the 8th, it is spent on crisis, inheritance, and sudden changes of rank. In the 12th, on foreign posts, expenses, and a father-story that lives at a distance. The Sun's mahadasha is only 6 years, so the solar activation is short. Rahu's 18 years are the longer activation of the same conjunction. Judge which one is running before you describe 'the' effect. Sunday discipline addresses the Sun. It does not pick the house. The house was chosen at birth.
Frequently asked questions
Does the 10th-house version ruin a career?
The Sun has directional strength in the 10th. Rahu makes the career unusual and contested. Ruin is a further reading, if the 10th lord is also weak. The conjunction alone is a loud career, not a cancelled one.
Why is the 9th version singled out?
Because the Sun, already the father karaka, then occupies the father house. Grahan in the 3rd or the 11th does not stack the karaka on its own bhava in that way.
Which mahadasha is longer for this yoga?
Rahu's, at 18 years. The Sun's own mahadasha is 6. Most of a life spent 'in' this yoga's dasha will be Rahu's period, with the Sun as a shorter chapter.
