Spiritual dabblers are hereby warned off, but the sincere are always welcome. Those who flit from craze to craze, or seek to satisfy their flirtatious souls at the expense of our strictly limited time, will do better by turning their faces due north, and not in my direction. If I am often excessively kind to innocent kittens, I can nevertheless be excessively cruel to humbugs. In this respect I am like the moon, for I wax quickly with friendly warmth to those who use words to explain their heart, and do not hide it; but I wane rapidly into arctic frigidity when the insincere approach me with a smile on their lips and something quite different in their breast.
