The first thing one must learn is to believe in the existence of such a thing as intuition. The next is to be able to follow one's intuition, even at the cost of something valuable. Even if one is deceived for some time, one will not continually be deceived. Therefore in the end one will find oneself on the right path. But the third thing is to make one's mind one-pointed by the help of concentration, which will permit one to perceive intuition properly. Just as for hearing the ears are so made that the voice waves resound in them and become clear, so the mind should be made a kind of capacity, or mold, in which the intuition may become clear. The difficulty is that outwardly the work of the ears is different from the work of the eyes; but the mind does both seeing and hearing at the same time.
