Crystal Therapy is the use of crystals to impact a person’s energetic body (also known as subtle body). One of the fundamental principals that crystal therapy depends on is the energy = light = information. Every thing on the planet emits energy; developing skills to become aware of this energy is key to using it in to our benefit.
Like all things, the human energy system emits information. We also absorb information from everything around us. There are many ancient systems of understanding the useable aspects of the human body, including the chakra system.
A skilled practitioner can assess your chakras and can use various tools and methods to balance your chakras. Chakras can be balanced through specific activities, by interacting with certain crystals, eating certain foods, applying specific essential oils, and listening to certain sounds. Each chakra resonates with a unique sound.
