Like a stone thrown into the water–Thought produces ripples and waves which spread out over the great Ocean of Thought. There is this difference, however: the waves on the water move only on a level plane in all directions–whereas thought-waves move in all directions from a common center, just as do the rays from the sun.
Just as we here, on Earth, are surrounded by a great sea of air–so are we surrounded by a great sea of Mind. Our thought-waves move through this vast mental ether–extending, however, in all directions, as I have explained–becoming somewhat lessened in intensity, according to the distance traversed, because of the friction occasioned by the waves coming in contact with the great body of Mind surrounding us on all sides.
The above quote is from the book Thought Vibrations by William Atkinson, this literature is part of The New Thought Movement. A movement based on the belief that the mind is powerful.
