Moon(Chandra) in twelth House
This house belongs to Moon.s friend Jupiter. Here the Moon will have good effects on Mars and the things associated with Mars, but it will harm its enemies Mercury and Ketu and the things associated with them. Hence the business and things associated with the house in which Mars is placed will provide highly beneficial effects. Similarly, the business and things associated with the houses where Mercury and Ketu are placed will be strongly damaged. The Moon in the 12th houses causes a general fear in the native.s mind about numerous unforeseen troubles and dangers and thus destroys his sleep and peace of mind. Ketu in the 4th house will become weak and affect the native.s son and mother very adversely.
