Ketu is a headless planet. It represents detachment, confusion, and a lack of clear direction. The 1st house (Lagna) represents the self, the ego, and the physical body.
When Ketu sits in the 1st house, the person lacks a strong, grounded sense of self. Because they are "headless" in their ego, they become hyper-sensitive to how others treat them. They will take offense at the smallest jokes, misunderstand innocent comments, and constantly sulk or hold grudges ("rooth jaya karta hai").
🪔 The VAYOM Remedy
If you have Ketu in the 1st house, you must realize that your mind is playing tricks on you. People are not always attacking you. Wear a silver chain around your neck to calm your mind and ground your ego.
