Are there any inherent dangers from having pyramids in the home? What about purchased pyramids?

There are no inherent dangers in having any pyramid structure in the living environment, and there can be some benefits in focusing energies from them if constructed properly and imbued with the right properties. The only danger from manufactured pyramids brought into the home environment is if they have been imbued with a dark energy for a nefarious purpose. This is sometimes the case with practitioners of black magic who wish to spread harm and will use such items as a vector to send their energy into the person’s environment, and the bonding to the person’s energy is done by them, and then they are rendered vulnerable. This is not a common practice, but does occur.
