To make my meaning plainer I will use an illustration. Take an author at his writing, a painter at his canvas, a composer listening to the melodies that dawn upon his glad imagination; let any one of these workers pass his daily hours by a wide window looking on a busy street. The power of the animating life blinds sight and hearing alike, and the great traffic of the city goes by like nothing but a passing pageant. But a man whose mind is empty, whose day is objectless, sitting at that same window, notes the passers-by and remembers the faces that chance to please or interest him. So it is with the mind in its relation to eternal truth. If it no longer transmits its fluctuations, its partial knowledge, its unreliable information to the soul, then in the inner place of peace already found when the first rule has been learned—in that inner place there leaps into flame the light of actual knowledge. Then the ears begin to hear. Very dimly, very faintly at first. And, indeed, so faint and tender are these first indications of the commencement of true actual life, that they are sometimes pushed aside as mere fancies, mere imaginings. But before these are capable of becoming more than mere imaginings, the abyss of nothingness has to be faced in another form. The utter silence which can only come by closing the ears to all transitory sounds comes as a more appalling horror than even the formless emptiness of space. Our only mental conception of blank space is, I think, when reduced to its barest element of thought, that of black darkness. This is a great physical terror to most persons, and when regarded as an eternal and unchangeable fact, must mean to the mind the idea of annihilation rather than anything else. But it is the obliteration of one sense only; and the sound of a voice may come and bring comfort even in the profoundest darkness. The disciple, having found his way into this blackness, which is the fearful abyss, must then so shut the gates of his soul that no comforter can enter there nor any enemy. And it is in making this second effort that the fact of pain and pleasure being but one sensation becomes recognisable by those who have before been unable to perceive it. For when the solitude of silence is reached the soul hungers so fiercely and passionately for some sensation on which to rest, that a painful one would be as keenly welcomed as a pleasant one. When this consciousness is reached the courageous man by seizing and retaining it, may destroy the “sensitiveness” at once. When the ear no longer discriminates between that which is pleasant or that which is painful, it will no longer be affected by the voices of others. And then it is safe and possible to open the doors of the soul.
