"(5) When you find the crystals begin to look dull or cloudy, with small pin-points of light glittering therein, like tiny stars, you may know that you are commencing to obtain that for which you seek, viz., crystalline vision. Therefore, persevere with confidence. This condition may, or may not, continue for several sittings, the crystal seeming at times to alternatively appear and disappear, as in a mist. By and by this hazy appearance, in its turn, will give way quite suddenly to a blindness of the senses to all else but a blue or bluish ocean of space, against which, as if it were a background, the vision will be clearly apparent. Physical Requirements. "(6) The crystal should not be used soon after taking a meal, and care should be taken in matters of diet to partake only of digestible foods, and to avoid alcoholic beverages. Plain and nourishing food, and outdoor exercise, with contentment of mind, or love of simplicity of living, are great aids to success. Mental anxiety, or ill-health, are not conducive to the desired end. Attention to correct breathing is of importance. Determining Time of Fulfillment. "(7) As regards the time at which events seen will come to pass, each seer is usually impressed with regard thereto; but, as a general rule, visions appearing in the extreme background indicate time more remote, either past or future, than those perceived nearer at hand; while those appearing in the foreground, or closer to the seer, denote the present or immediate future. Two Classes of Visions. "(8) Two principal classes of vision will present themselves to the sitter, viz.: (a) the Symbolic, indicated by the appearance of symbols such as a flag, boat, knife, gold, etc., and (b) Actual Scenes and Personages, in action or otherwise. Persons of a positive type of organization, the more active, excitable, yet decided type, are most likely to perceive symbolically, or allegorically; while those of a passive nature usually receive direct or literal revelations. Both classes will find it necessary to carefully cultivate truthfulness, unselfishness, gratitude for what is shown, and absolute confidence in the love, wisdom, and guidance of God Himself."
