Disappointed men find that food itself is not so sweet as dreams. The seamstress toiling in the attic stitches hope in with each thread, and dreams of some knight coming to lift her out of poverty, and her reverie mocks and consumes her woe. The laborer digging in his ditch sweetens his toil and rests his weariness by the dream of the humble home labor and love will some day build. Many in middle life, when it is too late, find themselves in the wrong occupation, but maintain their usefulness and happiness by surrounding themselves with the thoughts of the career they love and beyond may yet fulfill. How does imagination enterprise everywhither! By it what ships are built, what lands are explored, what armies are led, what thrones are erected in thought! When the seed sprang up in the prison cell, the scholar confined there enlarged the little plant until in his mind it became a vast forest, where all flowers bloomed and spiced shrubs grew and birds sang, and where brooks gurgled such music as never fell on mortal ear. Innumerable men endure by seeing things invisible. They retire from the vexations and disappointments without to their hidden-vision life. Their inner thoughts contrast strangely with the outer fact and life. During the Middle Ages, when persecution broke out against the Jews, these merchants were oppressed and robbed, and saved themselves from destruction only by living a squalid life outside and a princely life in hidden quarters. It has been said: "You might follow an old merchant, spotted and stained with all the squalor of beggary upon him, through byways foul to the feet and offensive to every sense, and through some narrow lane enter what looks like the entrance of an ill-kept stable. Thence opens out a squalid hall of noisome odors. But ascending the steps you come to a secret passage, when, opening the door, you are blinded with the brilliancy that bursts upon you. You are in the palace of a prince. The walls are covered with adornments. Rare tapestries hang upon the walls. The dishes that bespread the table are of silver and gold, and the household, who hasten to receive the parent and strip off his outward disguise, are themselves arrayed like king's children." Thus the ideals make a great difference between the man without and the hidden life within. Seeing unseen things, the heart sings while the hand works. The vision above lifts the life out of fatigue into the realm of joy and restfulness.
