It has sometimes been asked by doubtful critics if it would not be an improvement on nature's plan if the sorrow caused by the death of our friends were softened by direct knowledge of their continued existence. It is evidently the plan of nature to have the physical life and the astral life normally separated at our present level of evolution. Some of the reasons have already been discussed. There are undoubtedly others that we are incapable of understanding, and still others that we can readily comprehend. If the higher, joyous life of the astral world were open to our consciousness, then concentration upon the duties of this life would be difficult, if not impossible. Our life in the physical body may be compared to the tasks of children in school. They have serious business before them in the acquiring of knowledge and the development of the intellect. They can best accomplish the work when completely isolated from other phases of life. Introduce into their work-day consciousness the joys of a child's existence, the circus, the military parade, the picnic and the dancing parties, and the purpose for which the school exists would be defeated. To exactly the extent that the consciousness is withdrawn from such things will desirable progress be made with the work of the school-room. And so it is with the limitation of our physical senses. It serves a purpose. But there is a point in human evolution where such limitation of the senses is no longer of any service and may be transcended. Some people have attained it. They are those who have previously been referred to as the psychic scientists, with the higher clairvoyance of the cerebro-spinal system developed. It is an accomplishment to which all may aspire. None need submit to the separation commonly caused by death. By hard work in co-operating with nature's methods of evolution and by a serious and sustained effort to live the highest and most helpful life of which one is capable, it is possible in time to attain a level of consciousness where one has personal knowledge that the dead still live. But in the very work of rising to that level, the concentration previously enforced by the limitation of the physical senses will have been acquired.
