Book excerpt: We are a product of nature. Every single cell of our body is made of, and depends, on nature. Our inner soul is heavily influenced by nature. We feel sad if the sun is not shining for a few days, and feel pleasure when drawn to the wonder of flowers and uplifted by the song of birds. We came from nature; we are part of nature. In short, we are nature. Nature has been an intimate part of the human experience from the earliest times. Different religions and cultures, from all corners of the world, have honoured and worshipped nature in art, ritual and literature in their own unique ways. This book shows how we learn about our own human nature, our own sense of identity and how we fit into the larger scheme of life and spirit when we come to better understand how our human ancestors, through art, symbol and myth, expressed their relationship with the natural world.
