"The third way is the way of the yogi. This is the way of knowledge, the way of mind. The way of the yogi consists in working on the third room and in striving to enter the fourth room by means of knowledge. The yogi reaches the fourth room by developing his mind, but his body and emotions remain undeveloped and, like the fakir and the monk, he is unable to make use of the results of his attainment. He knows everything but can do nothing. In order to begin to do he must gain the mastery over his body and emotions, that is, over the first and second rooms. To do this he must again set to work and again obtain results by means of prolonged efforts. In this case however he has the advantage of understanding his position, of knowing what he lacks, what he must do, and in what direction he must go. But, as on the way of the fakir or the monk, very few acquire this understanding on the way of the yogi, that is, that level in his work on which a man knows where he is going. A great many stop at one particular achievement and go no further."
