The explanation of this disorder of the tone is that there is a certain tone which the breath vibrates throughout the body, through every channel of the body; and this tone is a particular tone, continually vibrating, in every person. And when the mystics have said that every person has his note, it is not necessarily the note of the piano, it is the note which is going on as a tone, as a breath. Now, if a person does not take care of himself and allows himself to be influenced by every wind that blows, he, like the water in the sea, goes up and down disturbed by the air. The normal condition is to be able to stand firm through fear, joy, and anxiety; not to let every wind blow one hither and thither like a scrap of paper, but to endure it all and to stand firm and steady through all such influences.
