The 2nd house represents family, accumulated wealth, and early childhood habits. Ketu is the planet of detachment, secrecy, and sometimes, rebellious behavior.
When Ketu is negative or afflicted in the 2nd house, it creates a very specific childhood trait. Dr. Sharma explains that this child becomes highly rebellious and completely fearless, not even fearing their own father ("pita se bhi na darta").
More surprisingly, they develop a habit of secretly stealing money or items from their own home ("ghar mein chori karta hai"). This is a karmic symptom of a bad Ketu that needs to be corrected early in life through proper guidance and remedies.
