By the study of this one will find that there are five different aspects which constitute our physical body. The mystics, for convenience, call them earth, water, fire, air, ether. But these must not be compared with the scientific terms; it is only for the convenience of a mystic. Then one will see the different senses, the organs of the senses: each sense represents one of these elements. And coming to the natural tendencies and needs of life, every action one does has a relation to one of these five elements. This study of the mechanism will make a person understand that something which he always called himself is nothing but a mechanism, a mechanism made of five elements, the elements which are borrowed from the outer world. And he will find that his mind, which experiences through all organs of the senses, still remains aloof as a spectator who conceives and perceives the outside world through the mediumship of this mechanism which he calls his body.
