Today, we understand that everything in the universe is a form of energy with its own, unique frequency and vibration, including crystals. Nikola Tesla has declared that this concept is the key to understanding the universe and has proven that certain forms of energy can alter the vibrational resonance of other forms of energy. This is why crystals are used by holistic healers to align, heal and raise the frequency and vibration of the whole body, which consists in all the 4 levels: physical, emotional, mental and spiritual.

Ancient cultures did not have access to the scientific information that we have access to today about the metaphysical power of crystals. However, people from around the world seem to be instinctively drawn to these wonderful gems and have a deeper understanding of their value and meaning in the universe.
