Henry David Thoreau's two years at Walden Pond were, above all, a personal experiment in mindfulness. He chose to put his life on the line in order to revel in the wonder and simplicity of present moments. But you don't have to go out of your way or find someplace special to practice mindfulness. It is sufficient to make a little time in your life for stillness and what we call nondoing, and then tune in to your breathing.
All of Walden Pond is within your breath. The miracle of the changing seasons is within the breath; your parents and your children are within the breath; your body and your mind are within the breath. The breath is the current connecting body and mind, connecting us with our parents and our children, connecting our body with the outer world's body. It is the current of life. There are nothing but golden fish in this stream. All we need to see them clearly is the lens of awareness.
