Pendulums

Pendulums are often used as tools for spiritual healing and inner growth. Defined as objects attached at the end of a string or metal chain, when suspended from a stationary position, a pendulum will swing back and forth or in a circular motion. 
Pendulums promote healing with the process of Dowsing which seeks out invisible energies. This connects people to higher energies spiritually and can help locate any blocks in energy.
They are used as a form of reflection by asking questions to receive guidance, awareness, and understanding.
Balancing one's chakras is also possible with pendulums, as pendulums tend to pick up on subtle vibrations to clear the body and balance mind, body, and spirit.
Thus, pendulum objects can help relieve forms of pain whether emotional or physical. To this end, it's important when using a crystal pendulum to choose a method of cleansing or clearing crystal prior to the divination session, whether it be for healing or dowsing for answers.
