There is a tendency to use spirituality to justify rather than explain. In other words, we start from a non-spiritual goal (or goals) and try to graft spirituality onto that. That's not spirituality, but a self-serving smokescreen.
Rather, a spiritual approach to environmental protection begins with the premise that there is a spiritual, or divine, foundation to the world and uses that lens to view environmental protection. In our view, that spiritual foundation is ancient and omnipresent. In using that spiritual lens, much like looking at a distant object via a telescope or a tiny object under a microscope, we are able to reveal the hidden details and the broader context of those details that we would be unable to discover without that "spiritual" lens.
This was the goal of the book, what we tried to add to the policy debate.
