Reiki is based on the belief that a natural flow of energy runs through every person. When this energy flows freely and is balanced, people tend to feel calm, grounded, and healthy. Stress, illness, or emotional difficulties can disrupt this flow, leading to feelings of tension, overwhelm, or imbalance. During a Reiki session, a practitioner uses light touch or holds their hands just above the body to gently guide energy. This process is subtle and relaxing rather than forceful or invasive.
