This book has no pretension to be a thorough, systematic study of the subject. It is more or less a collection of studies the author has written from time to time in the course of his readings, especially of Meister Eckhart as representative of Christian mysticism. For Eckhart's thoughts come most closely to those of Zen and Shin. Zen and Shin superficially differ: one is known as Jiriki, the "self-power" school, while the other is Tariki, the "other-power" school. But there is something common to both, which will be felt by the reader. Eckhart, Zen, and Shin thus can be grouped together as belonging to the great school of mysticism. The underlying chain of relationship among the three may not be always obvious in the following pages. The author's hope, however, is that they are provocative enough to induce Western scholars to take up the subject for their study.
The author wishes to acknowledge his debts to the two English translations of Meister Eckhart, the first by C. de B. Evans and the second by Raymond B. Blakney, from which he has very liberally quoted.
