Following upon these two ordinary points, there is a third, which is not necessary to all meditation, called by some the local representation, and by others the interior picture.
It is simply kindling a vivid picture of the mystery to be meditated within your imagination, even as though you were actually beholding it. For instance, if you wish to meditate upon our Lord on His Cross, you will place yourself in imagination on Mount Calvary, as though you saw and heard all that occurred there during the Passion; or you can imagine to yourself all that the Evangelists describe as taking place where you are.
