The pendulum can be thought of as an extension of the intuition, since it is used to gain access to information that exists at the subconscious level of the Inner Being. It could be said that it strengthens or amplifies the intuition because it converts the subtleties of the intuition into a more obvious form of physical motion. When you ask a question of the pendulum, it is your own intuition that answers it. The pendulum merely allows you to physically see what the intuition already knows. As an extension of the intuition, the pendulum can give you information from the same two sources as the intuition: from your own subconscious mind; and from your guidance, spirit, or guardian angel.
