The experience of oneness with other human beings would be incomplete and ineffective without an experience of oneness with the rest of the universe. We are not and could never be an isolated species. As human beings we are part of nature; we belong to the greater community of all living beings. More than that, the sun is our brother, the moon our sister, and the earth our mother. We belong to the great family of creation.
