Dr. Sharma exposes the deep hypocrisy and misplaced priorities of a person with Ketu in the 3rd house.
The 3rd house is the natural house of brothers. Because Ketu creates detachment and separation where it sits, this person develops a toxic dynamic with their own siblings.
To the outside world, this person acts like a saint. They will go out of their way to help strangers, friends, and outsiders ("har kisi ki madad ko haath badhata hai"). But when it comes to their own brothers, they are incredibly harsh, constantly criticizing and insulting them ("khari khoti sunata hai"). This misplaced charity destroys their own bloodline.
