"Like nearly all schools of the Mysteries, the teachings of the Druids were divided into two distinct sections. The simpler, a moral code, was taught to all the people, while the deeper, esoteric doctrine was given only to initiated priests. To be admitted to the order, a candidate was required to be of good family and of high moral character. No important secrets were entrusted to him until he had been tempted in many ways and his strength of character severely tried."
