Pendulums are great for a question and answer session. The best thing or advice that I can give you regarding a pendulum is that it connects to your energy field. That means there is an entrainment that happens where you and the object become one, everything that you know it has knowledge of. it then checks the surrounding energy fields for your answers and brings it back to you. This is why sometimes when you use a pendulum you have what you may deem dissonant energy with regard to the answer given. That just means that you can clear the energy go back and re-ask the question and do the inner work necessary to get to where it is that you would like to be.
