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.
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.
The ground under the Bilva tree is very holy. Meditating here quickly brings about an awakening of the religious instinct. Shri Ramakrishna used to say so.
