Connect with the earth: Walking barefoot in the wilderness to connect to the earth. While walking one would feel the hardness and softness of the soil, texture of the soil, warm and coolness of the soil based on the sunlight falling on the ground through the leaves, feeling the dry leaves. Avoiding the thorns by the feel of every step, feeling the slope of the land, feeling the sheet rocks, etc. With this exercise one could be present continuously and nothing else. It gives lots of peace through mindfulness. This exercise is also good for concentration and as a meditation, especially in the morning. The blood circulation also improves. The acupressure of the feet improves the health too.
