Rahu in the 10th, Karma Bhava

Rahu in the 10th house occupies karma bhava, the house of public work, status, and authority. The impact is ambition that will not sit inside an ordinary job title, often technical, foreign, media-facing, or slightly outside the family trade. Ketu falls in the 4th, so the home, the mother, and emotional ground carry detachment while the career carries hunger. The person can be famous in the office and thin at home, or can build a career precisely because the 4th is restless.

The 10th lord is still the manager. Rahu is the tenant. A strong 10th lord makes the unusual career durable. A debilitated 10th lord makes it loud and unstable.

Rahu mahadasha lasts 18 years. With Rahu in the 10th, those years are the obvious career period, especially Rahu-Rahu at the start and any antardasha of the 10th lord. The Sun, karaka of authority, and Saturn, karaka of labor, color the same house when their antardashas arrive inside the 18. Rahu-Sun can raise status quickly and politically. Rahu-Saturn can turn the rise into a long shift.

The Sun has directional strength in the 10th. Rahu in the 10th is not the Sun, so do not give Rahu the Sun's digbala. Give Rahu the house and keep the Sun's strength as a separate question.

A 10th-house Rahu can also describe a public image that outruns the skill, because Rahu inflates. The Navamsa of the 10th lord shows whether the career holds after the first visibility. Saturn in the 10th of the Navamsa would slow what birth-chart Rahu sped up.

Hessonite during this mahadasha strengthens the career node. That is coherent only if you want the 10th louder. It will not settle the Ketu 4th. Home and mother remain a 4th-house reading, Moon included, during the same years.
