In my seeking I try to understand what this means for my own spirituality and for the sacredness of the earth. I do know that my worship is the deepest when I am in the presence of the natural world, out in the desert or in the mountains. My spirit is nurtured by the presence of wild things. This does not mean that I will be a vegetarian. God is not just in all life, God is in the stones also.
Physicists see that humans and rocks are made of the same elements.
Biologists see a difference between rocks and life. This recognition is useful, therefore we recognize, we make the distinction. That of God could be there regardless of whether it is recognized. This is as far as I have gotten on this query. Light is not a thing to have.
