In terms of eco-spirituality, love leads us to identify ever more with the Earth, for love is the great unifying and integrating power of universe. For centuries we have thought about the Earth. We were the subject of thought, and the Earth was its object and content. After all that we have learned of the new cosmology, we must think of ourselves as Earth. Earth is the great living subject feeling, loving, thinking, and through us knowing that it thinks, loves and feels. Love leads us to identify with Earth in such a way that we no longer need to become aware of these things, for they have become second nature, Then we can be mountain, sea, air, road, tree, animal, We can be one with Christ, with the Spirit, and ultimately with God.
— Leonardo Boff, Cry of the Earth, Cry of the Poor
