Selenite is a crystallized form of gypsum and a very soft stone that should be kept dry. It is a master crystal and you do not need to activate this particular stone for it to work for you. It is intuitive binding working directly with your personal energies. It can also used to charge other stones. I think Selenite is by far one of the best when it comes to clearing away negative energy.
Selenite, effectively absorbs negative energy from any space and person, removes energy blockages, balances the emotions, and brings about mental clarity. The powerful vibration of Selenite opens the Crown Chakras and is excellent for meditation and spiritual work. Use selenite around your home in the corners of a room to create a safe and peaceful space or keep it within a foot of your bed to promote restful sleep. I have one on my nightstand near my bed, on my desk at work, in my purse and on the dashboard of my car. As an added bonus Selenite is said to reverse the effects of “free radicals” to heal and repair the body on a cellular level.
