Pendulums are tools used in divination. They are often used to connect with the spirit world and to get an answer to yes/no questions. Crystal pendulums can often be used to detect blockages in one’s path, for healing and for balancing the seven chakras.
Throughout history pendulums have been used to locate water, gold, gems, and other valuable items.
In some cases, they are also used for scrying on ones future, finding something that has been lost or seeking divine intervention on decisions to be made.
