Selenite is a form of gypsum with an obvious crystalline structure. Its soft light provides clarity of mind and expands one's awareness of self. It is also effective at clearing congested energies or negativity from one's field and is ideal for meditation and spiritual work as it enhances telepathy.
Pendulums have been used for ages for divination and determining the answer to any question which the rational mind cannot perceive. This is accomplished by allowing the body, through a process known as "muscle testing," to determine the outcome. Simply ask a question to which you know the answer to determine which circular or horizontal/vertical "+" motion is yes or no. Get relaxed, then ask your question!
Please note that due to natural variations in gemstone deposits, the pendulum you receive may not be identical to the one pictured.
