MY DEAR CHILD,--how your mind has grown since you left me, the sanguine and aspiring votary of an art which, of all arts, brings the most immediate reward to a successful cultivator, and is in itself so divine in its immediate effects upon human souls! Who shall say what may be the after-results of those effects which the waiters on posterity presume to despise because they are immediate? A dull man, to whose mind a ray of that vague starlight undetected in the atmosphere of workday life has never yet travelled; to whom the philosopher, the preacher, the poet appeal in vain,--nay, to whom the conceptions of the grandest master of instrumental music are incomprehensible; to whom Beethoven unlocks no portal in heaven; to whom Rossini has no mysteries on earth unsolved by the critics of the pit,--suddenly hears the human voice of the human singer, and at the sound of that voice the walls which enclosed him fall. The something far from and beyond the routine of his commonplace existence becomes known to him. He of himself, poor man, can make nothing of it. He cannot put it down on paper, and say the next morning, "I am an inch nearer to heaven than I was last night;" but the feeling that he is an inch nearer to heaven abides with him. Unconsciously he is gentler, he is less earthly, and, in being nearer to heaven, he is stronger for earth. You singers do not seem to me to understand that you have--to use your own word, so much in vogue that it has become abused and trite--a mission! When you talk of missions, from whom comes the mission? Not from men. If there be a mission from man to men, it must be appointed from on high.
