Pyrite is a powerful protection stone that works on the physical, etheric, and emotional levels to shield and protect from all types of bad vibrations and/or energy. It stimulates the mind and improves memory, making it easier to recall important information when needed. Pyrite aids in looking past the surface of things, encouraging an awareness of what is underlying words and deeds. Pyrite is said to have several therapeutic properties. It has the potential to improve both physical and mental well-being. 
Spiritually, this stone assists you in fully healing by accepting yourself as you are. The Pyrite stone guarantees a continual flow of good energy for this aim. Then, through boosting energy and awareness, it aids your spiritual evolution. Pyrite's purpose is to keep you strong, stable, and free of the chains of domination. It appears to have an intuitive quality that helps to keep you safe — spiritually and emotionally. In Feng Shui, pyrite crystals give out Earth and Fire energies. For Earth energy, place a pyrite mirror, figure, or bowl of tumble stones at the northeast and southwest corners of your home. This sort of energy is associated with love, relationships, education, and abilities. It will offer a sense of security and safety when put in resting locations. Pyrite can be placed in the south of a home to offer Fire energy. Yang energy, warmth, excitement, and a sense of well-being will be attracted to it.
