It is the voice of man which shows whether a person is hard or tender, wilful or weak-willed; every characteristic of man can be perceived through his voice. The grade of the person's evolution, his tendency and his condition at that moment can be realized by his voice. This shows that, before the face, the expression or the movement, the word can convey a feeling or a condition. It shows that the real being of man, the central point of his life is to be found in the breath, for voice is only an expression of breath. When this voice is expressed outwardly, it is in the form of words.
