As the thought-world is the experience of life itself, indeed is life itself, it cannot be expressed in weights and measures, in degrees of vibrations or wavelengths, for such results are no more than dead or lifeless phenomena. They do not explain what or who that "Something" is that perceives the thought as desire and will, as sorrow and joy, that "Something" that desires the solving of the mystery of thought, that "Something" that explains matter in terms of weights and measures. Can a stone, can water or air, or a combination of any of the physical ingredients of these substances, think, desire, will, speak and act, feel joy and sorrow, pleasantness or unpleasantness? As long as it is a fact that there is "Something" in existence that can sense, desire, speak and act, feel hunger and satiation, feel joy and sorrow, it is also a fact that there is more between heaven and earth than just stone, water, and air, and that everyone who denies this denies facts and is, in this particular area, still only a "layman". Such a being is still, in the area of the study of life itself, quite an inept being to whom tribute is paid in superstition, whether he be a professor, a doctor or in any other way a representative of a wide material study.
