Those who will not do so have chosen the place of pause arbitrarily, and there is nothing to be done but let them remain there undisturbed, working that treadmill which they believe to be the utmost activity of existence. II There is no doubt that a man must educate himself to perceive that which is beyond matter, just as he must educate himself to perceive that which is in matter. Every one knows that the early life of a child is one long process of adjustment, of learning to understand the use of the senses with regard to their special provinces, and of practice in the exercise of difficult, complex, yet imperfect organs entirely in reference to the perception of the world of matter. The child is in earnest and works on without hesitation if he means to live. Some infants born into the light of earth shrink from it, and refuse to attack the immense task which is before them, and which must be accomplished in order to make life in matter possible. These go back to the ranks of the unborn; we see them lay down their manifold instrument, the body, and fade into sleep. So it is with the great crowd of humanity when it has triumphed and conquered and enjoyed in the world of matter. The individuals in that crowd, which seems so powerful and confident in its familiar demesne, are infants in the presence of the immaterial universe. And we see them, on all sides, daily and hourly, refusing to enter it, sinking back into the ranks of the dwellers in physical life, clinging to the consciousnesses they have experienced and understand. The intellectual rejection of all purely spiritual knowledge is the most marked indication of this indolence, of which thinkers of every standing are certainly guilty.
