In addition to the outer aspects of these processes, there is also an inner aspect. The author shows that the process of growth through the seven phases is essentially a process of spiritual development. Spirit manifests in human beings and determines the meaning and direction of our lives, providing motivation for change and direction. These impulses also work in groups and organizations, and understanding them gives us greater insight.
Van den Brink's approach offers a refreshing, new, and dynamic way forward in contrast to the rationalistic methods of most mainstream consultants and personal development.
