It recently struck me that people don't use their pendulums to the full capacity. Other than yes/no answers, a lot of people don't realise that pendulums can be used for many things.
For example, I have used my pendulum as a conductor to direct intent to somebody over a long distance. I have also used it to send messages to people in the form of dreams and receive a dream somebody is having while remaining conscious. I'm sure it can be used for many more things. What have you used your pendulum for?
