Ketu is the planet of ultimate detachment. When it sits in the 2nd house (wealth and family), any form of intense attachment becomes a curse.
Dr. Sharma warns that a person with Ketu in the 2nd house must never become greedy for money, nor should they become obsessively greedy for love and relationships ("na paise ka lalach... na pyaar ka"). If they chase these, Ketu will destroy them.
If they must have a "greed" or passion, it should only be for the "four directions" ("dishayein chaar ka")βmeaning a passion for travel, exploration, and spiritual wandering. Embracing movement brings them peace; hoarding brings them pain.
