A great many people believe that the mind is so powerful it can literally think of anything. But that’s not true. For example – imagine in your mind, the sound of the lowest possible musical note; an extremely deep bass made by any instrument or device you can think of. Keep imagining that note and imagine it as infinitely deep as you can. Now … think of a deeper note. Music, something you can easily hear in your mind is limited by the mind. Why? How?
