HOW TO BEGIN
The best thing to do is to try these various methods, and then see for yourself which is the most successful in your own individual case.
Here are a few means you might try, in order to test this for yourself.
Use either a (1) crystal, (2) a polished object, (3) a bright coin, (4) a sparkling gem, or (5) ordinary glass in the shape of a sphere or ball. There are others, but they are not important.
In conclusion, it will be of interest to know just what you may expect to see when, and if, your spirit eyes open. Probably a misty, fogged appearance will first be seen in the crystal. This will remain for some little time, until finally the scene or person (whatever it may be) will appear. The latter may be faint and dim, or it may be clear-cut like a good photograph.
The clearness or otherwise will depend among other things upon the keenness of sight of the spirit eye. It will also be influenced by the degree of quiet, and upon the absence of anything likely to disturb the searcher in the realms of the future.
