If you can't explain what you are doing to a nine-year-old, then either you still don't understand it very well, or it's not all that worthwile in the first place.
Albert EinsteinA person experiences life as something separated from the rest - a kind of optical delusion of consciousness. Our task must be to free ourselves from this self-imposed prison, and through compassion, to find the reality of Oneness.
Albert EinsteinWhen the number of factors coming into play in a phenomenological complex is too large scientific method in most cases fails. One need only think of the weather, in which case the prediction even for a few days ahead is impossible. Nevertheless, no one doubts that we are confronted with a causal connection whose causal components are in the main known to us. Occurrences in this domain are beyond the reach of exact prediction because of the variety of factors in operation, not because of any lack of order in nature.
