This is an incredibly rare and brilliant physical observation from Lal Kitab regarding Ketu in the 1st house.
Ketu represents uniqueness, breaking the mold, and sometimes, the left side of the body. Dr. Sharma reveals that if a person with Ketu in the 1st house is naturally left-handed ("lefty hua"), they are born with extraordinary, genius-level potential.
Being left-handed perfectly aligns their physical body with Ketu's energy. This makes their Ketu so powerful that it completely dominates and controls Rahu (which sits opposite in the 7th house). They will achieve such massive success that it will feel like an "earthquake" ("bhoochaal kar dega") in their industry.
