_Conversions_, whether they be political, scientific, philosophic, or religious, form another way in which bound energies are let loose. They unify us, and put a stop to ancient mental interferences. The result is freedom, and often a great enlargement of power. A belief that thus settles upon an individual always acts as a challenge to his will. But, for the particular challenge to operate, he must be the right challeng_ee_. In religious conversions we have so fine an adjustment that the idea may be in the mind of the challengee for years before it exerts effects; and why it should do so then is often so far from obvious that the event is taken for a miracle of grace, and not a natural occurrence. Whatever it is, it may be a highwater mark of energy, in which "noes," once impossible, are easy, and in which a new range of "yeses" gains the right of way. We are just now witnessing a very copious unlocking of energies by ideas in the persons of those converts to "New Thought," "Christian Science," "Metaphysical Healing," or other forms of spiritual philosophy, who are so numerous among us to-day. The ideas here are healthy-minded and optimistic; and it is quite obvious that a wave of religious activity, analogous in some respects to the spread of early Christianity, Buddhism, and Mohammedanism, is passing over our American world. The common feature of these optimistic faiths is that they all tend to the suppression of what Mr. Horace Fletcher calls "fearthought." Fearthought he defines as the "self-suggestion of inferiority"; so that one may say that these systems all operate by the suggestion of power. And the power, small or great, comes in various shapes to the individual,--power, as he will tell you, not to "mind" things that used to vex him, power to concentrate his mind, good cheer, good temper--in short, to put it mildly, a firmer, more elastic moral tone. The most genuinely saintly person I have ever known is a friend of mine now suffering from cancer of the breast--I hope that she may pardon my citing her here as an example of what ideas can do. Her ideas have kept her a practically well woman for months after she should have given up and gone to bed. They have annulled all pain and weakness and given her a cheerful active life, unusually beneficent to others to whom she has afforded help. Her doctors, acquiescing in results they could not understand, have had the good sense to let her go her own way.
