The 10th house is the house of career, karma, and hard work (ruled naturally by Saturn). When Ketu (the planet of detachment and headless wandering) sits here, it creates a massive professional flaw.
Dr. Sharma bluntly states that a person with an afflicted Ketu in the 10th house absolutely despises hard, physical labor ("nahi kaam tere bas ka"). They lack the discipline and stamina required to build a career from the ground up.
Instead, they suffer from an addiction to luxury, comfort, and taking the easy way out ("aaram aur aish ka hai chaska"). They want the rewards of the 10th house without putting in the Saturnian effort, which often leads to professional failure.
