Pendulums promote healing with the process of dowsing which seeks out invisible energies. This connects people to higher energies spiritually and can help locate any blocks in energy.

They are used as a form of reflection by asking questions to receive guidance, awareness, and understanding.

Balancing one's chakras is also possible with pendulums, as pendulums tend to pick up on subtle vibrations to clear the body and balance mind, body, and spirit.

All crystals hold different energies. 

Find one that resonates with you, and trust your guidance
