Place before you the small seed of a plant. It is then necessary, while contemplating this significant object, to create with intensity the right kind of thoughts, and through these thoughts to develop certain feelings. In the first place, let the student clearly grasp what is really presented to his vision. Let him describe to himself the shape, color, and all other qualities of the grain of seed. Then let his mind dwell upon the following train of thought: "This grain of seed, if planted in the soil, will grow into a plant of complex structure." Let him clearly picture this plant to himself. Let him build it up in his imagination. And then let him reflect that the object now existing only in his imagination will presently be brought into actual physical existence by the forces of the earth and of light. If the thing contemplated by him were an artificially-made object, though such a close imitation of nature that no external difference could be detected by human eyesight, no forces inherent in the earth or light could avail to produce from it a plant. He who thoroughly grasps this thought and inwardly assimilates it will also be able to form the following idea with the right feeling. He will reasons thus: "That which is ultimately to grow out of this seed is already, as a force, now secretly enfolded within it. The artificial duplicate of the seed contains no such force. And yet both appear to be alike to my eyes. The real seed, therefore, contains something invisible which is not present in the imitation." It is this invisible something on which thought and feeling are now to be concentrated.[10] Let the student fully realize that this invisible something will later on translate itself into a visible plant, perceptible by him in shape and color. Let him dwell upon the thought: "_The invisible will become visible._ If I could not think, then I could not now realize, that which will become visible later on." [10] Anyone who might object that a microscopical examination would reveal the difference between the two would only show that he has failed to grasp the intention of the experiment. The intention is not to investigate the physical structure of the object, but to use it as a means for the development of psychic force.
