Something resembling the mystic belief which Zen embraces is found in many countries and under many names. But Zen differs from other religions of the same kind in that it admits only one means by which the perception of Truth can be attained. Prayer, fasting, asceticism--all are dismissed as useless, giving place to one single resource, the method of self-hypnosis which I have here described. I have, indeed, omitted any mention of an important adjunct of Zen, namely tea-drinking, which was as constant a feature in the life of Zen monasteries as it is here in the régime of charwomen and girl-clerks. I have not space to describe the various tea-ceremonies. The tendency of monasteries was to create in them as in every part of daily life a more and more elaborate ritual, calculated to give some pattern to days otherwise devoid of any incident. We possess minute descriptions of every ceremony--the initiation of novices, the celebration of birth and death anniversaries of the Patriarchs, the procedure in cases of sickness, madness, disobedience, disappearance or death of monks; the selection and investiture of abbots; the lectures, liturgies and sessions which constituted the curriculum of Zen instruction. In China decay set in after the fifteenth century. The Zen monasteries became almost indistinguishable from those of popular, idolatrous Buddhism. In Japan, on the other hand, Zen has remained absolutely distinct and is now the favourite creed of the educated classes. It has not hitherto conducted any propaganda in Europe, whereas the Amida Sect has sent out both missionaries and pamphlets. But I believe that Zen would find many converts in England. Something rather near it we already possess. Quakerism, like Zen, is a non-dogmatic religion, laying stress on the doctrine of Immanence. But whereas the Quakers seek communion with the Divine Spark in corporate meditation and deliberately exploit the mysterious potencies of crowd-psychology--the Zen adept probes in solitude (or at least without reference to his neighbour) for the Buddha within him. In cases where a Quaker meeting passes in silence, the members having meditated quietly for a whole hour, a very near approach to a Zen gathering has been made. But more often than not the Holy Spirit, choosing his mouthpiece with an apparent lack of discrimination, quickly descends upon some member of the meeting. The ineffable, which Zen wisely refused to express, is then drowned in a torrent of pedestrian oration.
