We are more like onions. Onions have skins and layers of skin. We keep peeling it and a time comes nothing remains other than empty space! We too have layers and layers of our consciousness from solid gross to subtlest atoms, we never know this reality until we first come to hear about this higher truth and then ponder over this and match the physical sciences with metaphysical experiences. String theory is coming to conclude that matter is as such nothing but light. Mystics and mad-lovers of God, see no matter but God the light in everything. Meditation peels the layers and then takes you to the core where the empty space is pure silence and the Source of all Existence. The Existence is Pure Bliss.
