each volume is not going to be of equal interest to everyone.
What’s important is that Origen, Julian of Norwich, Sharafuddin Maneri, Menahem Nahum, and several dozen other mystics and spiritual masters are now easily accessible and accorded equal stature. The books are all attractively designed, nicely printed, and modestly priced, and available individually or by subscription. The series, which is now up to fifty volumes, has been going for several years at the pace of approximately one book a month. If your local library isn’t already acquiring the series as they appear, I’d suggest they catch up: books such as these are what libraries are for.
