Everything - a bird, a tree, even a simple stone, and certainly a human being - is ultimately unknowable. This is because it has unfathomable depth. All we can perceive, experience, think about, is the surface layer of reality, less than the tip of an iceberg. Underneath the surface appearance, everything is not only connected with everything else, but also with the Source of all life out of which it came. Even a stone, and more easily a flower or a bird, could show you the way back to God, to the Source, to yourself.
Eckhart TolleThis is the essence for every human being to realize that who they are, essentially, is far more than the physical body and is far more than the mental body, the psychological makeup, the psychological "me" body. Who they are is far deeper than that.
Eckhart TolleThe equivalent of external noise is the inner noise of thinking. The equivalent of external silence is inner stillness.
Eckhart Tolle
