Practical Mysticism 

Those who are interested in that special attitude towards the universe which is now loosely called ‚mystical, ‚ find themselves beset by a multitude of persons who are constantly asking–some with real fervour, some with curiosity, and some with disdain–‚What is mysticism?‘ When referred to the writings of the mystics themselves, and to other works in which this question appears to be answered, these people reply that such books are wholly incomprehensible to them.On the other hand, the genuine inquirer will find before long a number of self-appointed apostles who are eager to answer his question in many strange and inconsistent ways, calculated to increase rather than resolve the obscurity of his mind. He will learn that mysticism is a philosophy, an illusion, a kind of religion, a disease; that it means having visions, performing conjuring tricks, leading an idle, dreamy, and selfish life, neglecting one’s business, wallowing in vague spiritual emotions, and being ‚in tune with the infinite.‘ He will discover that it emancipates him from all dogmas–sometimes from all morality–and at the same time that it is very superstitious. One expert tells him that it is simply ‚Catholic piety, ‚ another that Walt Whitman was a typical mystic; a third assures him that all mysticism comes from the East, and supports his statement by an appeal to the mango trick. At the end of a prolonged course of lectures, sermons, tea-parties, and talks with earnest persons, the inquirer is still heard saying–too often in tones of exasperation–‚What is mysticism?‘
