The study of what has come to be known as esotericism is frustrating for countless reasons. The first of these is the number of charlatans and fraudsters who swarm in this field. Then there is the tedious universe that surrounds it. But above all, it is because esotericism does not deliver what it promises that it becomes more frustrating. At least, the student does not find fulfillment in it, and only discovers this after much study, and often after something worse. However, it would be untrue to classify this as a vain study. “Esotericism” has appropriated a tradition that, without it, would have been almost forgotten. But beyond that: after thousands of pages, one realizes that something has been learned. And even if, during the process, such learning has not been evident, the study itself, perhaps using the pages as intermediaries or as inspiration, gives the final impression of having revealed something of value.
