Dr. Sharma uses a brilliant predator-prey analogy to explain the professional failure of Ketu in the 10th house.
The 10th house is the natural domain of Saturn (Shani), the planet of hard work, discipline, and karma. Ketu is represented by a mouse. When Ketu sits in Saturn's house, Saturn acts like a snake ("saamp Shani ban jaata hai") demanding rigorous effort.
Because Ketu (the mouse) is terrified of Saturn's demands for discipline and hard labor, the native constantly runs away from responsibilities. Instead of facing challenges, they hide in their comfort zone ("bil mein chhip jaata hai"), ultimately destroying their own career out of sheer laziness and fear.
