How do chakra stones work and is there any science that can help me understand them better?

Namaste, Ananya. As a science teacher, you will appreciate the Electromagnetic Perspective. The Biofield: Science now recognizes the "Biofield"—a field of energy and information that surrounds the human body. The heart, for example, produces the largest electromagnetic field in the body, which can be measured several feet away. Crystalline Resonance: Crystals are Oscillators. In every computer, watch, and cell phone, there is a quartz crystal. Why? Because when you apply pressure (like the pressure of being on a human body), they produce a precise, consistent electronic frequency. The Quantifiable Link: When a crystal is within our biofield, its consistent "pulse" interacts with our own. This is not "magic"; it is Sympathetic Resonance. Just as one tuning fork will start to vibrate if another nearby is struck, our endocrine system (which correlates to the chakras) responds to the stable "pulse" of the crystal. This has been observed in studies involving the biophoton emission of living cells in the presence of various minerals.
