Dr. Rishi Rohit Sharma reveals a highly specific and dangerous Vastu-Astrology combination regarding Ketu in the 6th house.
The 6th house is the house of enemies, debts, and diseases. When Ketu sits here in a debilitated (neech) state, it directly attacks the Moon (peace of mind and liquid cash).
Dr. Sharma warns of a massive mistake people make with this placement: building a dedicated temple or shrine inside their home ("ghar mein jo mandir banaye"). Because Ketu 6 is highly malefic, establishing a permanent religious structure inside the house activates its negative energy, leading to the complete destruction of the native's wealth and savings ("paisa nasht kar deta hai"). Keep your worship simple and avoid large home temples.
