Concentration in the silence without effort is the state of consciousness of perfect calm, accompanied by the complete relaxation of the nerves and muscles of the body. One may say that the entire being becomes like the surface of calm water, reflecting the immense presence of the starry sky and its indescribable harmony.
And the waters are deep, so deep! And the silence grows, ever increasing. . . What silence! . . . One wave of silence followed by another wave of more profound silence, then again a wave of still more profound silence.
Have you ever DRUNK SILENCE? If so, you know what meditation without effort is.
There comes a pause, for human strength will not endure to dance without cessation; and everyone must reach the point at length of absolute prostration.
~ William Wordsworth in "The Prelude" from THE POETICAL WORKS OF WILLIAM WORDSWORTH
