A pendulum is an object suspended on a thread or chain through which the energy from the human energetic system flows. This flow of energy creates the movement of pendulum. The pendulum has the ability to receive as well as generate energy. Therefore, they can be used either as a sender or receiver.

Pendulums can be made of many different materials and may have different sizes or shapes. The most advanced and sought after pendulums are those, which are based on Sacred Geometry--the ancient Egyptian knowledge about shapes and their vibrations.
