One must be able to look at one's mind just as at a slate placed before one. While looking at it one must be able to shut oneself off from all sides, fixing one's mind solely upon one's inner being. By developing concentration, by stilling the mind, one can be tuned to the pitch which is necessary to perceive intuition. Besides, if one has once been disappointed in perceiving one's intuition, one must not lose courage; one must go on following it even if it continues to be a mistake. If one continually follows one's intuition then one will come to the right perception of it.
