From each heart is a window to other hearts
They are not separated like two bodies,
Just as, even though two lamps are not joined,
Their light is united in a single ray.
~ Jalaluddin Rumi
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.
