This is an insight meditation with the anchor being the sensations of the body. It emphasizes having the courage to feel, love, and accept all feelings, be they pleasant, unpleasant, or neutral. By accepting them and seeing the good in them, we can experience them in a relaxed, calm, and objective manner. By experiencing emotions in a relaxed, calm, and objective manner, the emotions are able to freely move and be released from the body instead of becoming trapped emotional energy.
