My daughter and her fiancée moved into a house that belonged to his parents. After two years they are finally solvent and wish to put their own stamp on the house. On the front of the house is a horoscope house talisman. My daughter wishes to remove it and replace it with a new one. (more Modern) She has been told that it is very bad luck to remove the talisman with out a blessing or ceremony. Can anyone help me please. I would be very grateful.

If you don't want to bother trying to find someone to bless it, you could just "bless" it yourself. Everything comes with it's own energy, and we all put out energy ourselves. So as long as your not taking it down while putting out a negative energy by thinking that it will bring bad luck it should be fine. For a little extra positive energy you could thank the talisman for all it's done but you are not longer in need of it anymore.
