In the present-day revival of interest in crystal-gazing among the wealthier classes of Europe and America, some of the high-priced teachers have insisted upon their pupils purchasing pure crystal globes, claiming that these alone are capable of serving the purpose fully. But, as such crystals are very expensive, this advice has prevented many from experimenting. But, the advice is erroneous, for any globe of clear quartz, or even moulded glass, will serve the purpose equally well, and there is no need of spending twenty-five to fifty dollars for a pure crystal globe. For that matter, you may obtain very good results from the use of a watch-crystal laid over a piece of black velvet. Some, today, use with the best effect small polished pieces of silver or other bright metal. Others follow the old plan of using a large drop of ink, poured into a small butter plate. Some have small cups painted black on the inside, into which they pour water--and obtain excellent results therefrom. Above all, I caution the student to pay no attention to instructions regarding the necessity of performing incantations or ceremonies over the crystal or other object employed in crystal-gazing. This is but a bit of idle superstition, and serves no useful purpose except, possibly, that of giving the person confidence in the thing. All ceremonies of this kind have for their purpose merely the holding of the attention of the person investigating, and giving him confidence in-the result--the latter having a decided psychological value, of course. There are but few general directions necessary for the person wishing to experiment in crystal gazing. The principal thing is to maintain quiet, and an earnest, serious state of mind--do not make a merry game of it, if you wish to obtain results. Again, always have the light behind your back, instead of facing you. Gaze calmly at the crystal, but do not strain your eyes. Do not try to avoid winking your eyes--there is a difference between "gazing" and "staring," remember. Some good authorities advise making funnels of the hands, and using them as you would a pair of opera glasses. In many cases, a number of trials are required before you will be able to get good results. In others, at least some results are obtained at the first trial. It is a good plan to try to bring into vision something that you have already seen with the physical eyes--some familiar object. The first sign of actual psychic seeing in the crystal usually appears as a cloudy appearance, or "milky-mist," the crystal gradually losing its transparency. In this milky cloud then gradually appears a form, or face, or scene of some kind, more or less plainly defined. If you have ever developed a photographic film or plate, you will know how the picture gradually comes into view.
