My religion is the Earth, man. I believe in trees.
Ecology and spirituality are fundamentally connected, because deep ecological awareness, ultimately, is spiritual awareness.
At the deepest level of ecological awareness you are talking about spiritual awareness. Spiritual awareness is an understanding of being imbedded in a larger whole, a cosmic whole, of belonging to the universe.
The Earth itself is stepping in to aid in the agenda of cultural transformation. There are too many doorways in nature that lead to heaven, there are too many paths to the mystery for any institution or social policy to be able to thwart the intent of the human species to evolve.
The earth is literally our mother, not only because we depend on her for nurture and shelter but even more because the human sepcies has been shaped by her in the womb of evolution. Our salvation depends upon our ability to create a religion of nature.
The Goddess does not rule the world; She is the world.
When the concept of human spirit is understood as the mode of consciousness in which the individual feels connected to the Cosmos as a whole, it becomes clear that ecological awareness is spiritual in its deepest sense.
