The body scan meditation involves lying down and focusing attention on different parts of the body while breathing. The meditation guide instructs the practitioner to focus on breathing and how it flows through the body. When the mind wanders, gently return attention to the area of focus. The guide then leads the practitioner through a full body scan, having them focus on sensations in each body part from toes to face, observing without judgment. The goal is to relax and release tension while gaining awareness of physical sensations throughout the body.
