When we look at life with a philosopher's view we see that every person is like one note in this symphony of life; that we all make this symphony of life, each contributing the music which is needed in that symphony. But if we do not know our own part in the symphony of life, naturally it is as if one of the four strings on the violin is not tuned, and if it is not tuned it cannot give the music which it should produce. So we must each produce that part for which we are born. If we do not contribute what we are meant to and what we should contribute, we are not in tune with our destiny. It is only by playing that particular part which belongs to us that we shall get satisfaction.
