" It is time, therefore, that you should apply for aid to such helpful Spirits. But will you have the strength of mind, the courage to endure the approach of Beings so different from mankind? I know that their coming produces certain inevitable effects, as internal tremors, the revulsion of the blood from its ordinary course; but I also know that these terrors, these revulsions, painful as they undoubtedly are, must appear as nothing compared with the mortal pain of separation from an object loved greatly and exclusively. "
