The body is a sensing instrument of consciousness. Without the body and mind,
the trees could not see themselves. Usually we think that we are looking at a tree, but the tree is looking at itself through us. Without this instrument, the tree does not get to see itself. We are sensing instruments of the Divine.
A sapling must be hedged about for protection, but when it becomes a tree, a hedge would be a hindrance. So there is no need to criticise and condemn the old forms.
We are sinful not only because we have eaten of the Tree of Knowledge, but also because we have not yet eaten of the Tree of Life. The state in which we are is sinful, irrespective of guilt.
