This looks like a beautiful book. I had not heard of the name "lotus birth" or considered the placenta a chakra, but I like the idea a lot! I did keep my placenta to bury it under a tree (sadly not a very gentle birth of a little person who didn't really feel like coming out much down to earth - a part of the whole autism syndrome). Sadly the neighbours protested. But still for the very thought of it, I feel it was energetically sanctified nonetheless.
I admire your honest postings of late about pain and doubt and all that equally rewarding side of living a spiritual life.
