Dr. Sharma reveals a highly specific, conditional Lal Kitab rule regarding Ketu in the 3rd house.
The 3rd house represents courage, short journeys, and younger siblings (ruled by Mars and Mercury). Ketu is generally considered debilitated or uncomfortable here, often causing issues with siblings or a lack of courage.
However, Dr. Sharma provides the "exception to the rule." If the native has exactly three siblings (brothers or sisters), this specific numerical alignment neutralizes Ketu's negative effects. Instead of acting debilitated ("neech nahi"), Ketu becomes highly auspicious, bringing immense courage, spiritual growth, and overall well-being ("karta hai bhalai") to the native.
