Friedrich Nietzsche has declared that God is dead. Matter has been found not to exist at all. This insight into matter brings modern physics very close to mysticism, very close. For the first time the scientist and the mystic are coming very close, almost holding hands. Matter is more like a thought than like a thing.
Existence is energy.
Science has discovered that the observed is energy, the object is energy. Your body is energy, your mind is energy, your soul is energy. The difference is only of a different rhythm, different wavelengths, that's all. Your thoughts are privately visible. But ordinarily they are not visible to others.
