*(The one with Rahu in the 10th has a fondness for sparkling water, or else a fondness for intoxication, cigarettes, or a quarter (alcohol) during work.)*
The 10th house is the house of career, karma, and public image. Rahu is the planet of illusion, smoke, and addiction.
When Rahu sits in the 10th house, it directly affects how a person works. Dr. Sharma reveals a very specific physical *Nishaniya*. This person will have a strange fondness for fizzy, carbonated drinks ("sparkling water").
More dangerously, they often develop a habit of consuming intoxicants *while* working. They feel they need a cigarette, a drink ("quarter"), or some form of smoke/nasha to concentrate on their job. This habit slowly destroys their professional reputation and invites the wrath of Saturn (the natural lord of the 10th).
