One must develop a certain obliquity of conscience, an elastic attitude toward the truth, to be effective in diplomacy.
The “secrets” (or arcane truths) imparted in this Degree are explained as consisting of certain peculiar marks or signs, intended to distinguish all Brethren of the elementary grade of Apprentice. Outwardly, in this and in subsequent Degrees also, they are expressed by step, sign, and word. These, of course, are not the full or real secrets, but only figurative emblems of them. It is what they signify that constitutes the secrets, and that significance is left for the Candidate to meditate upon and reduce into daily personal practice. Only so will he really learn them and come to understand why they are called “secrets” and why we insist upon their use. They can never be orally communicated, except in symbolic form, but must be learned by experimental practice.

“Astral” Beings may thus be defined in the same way as “material objects”; they are the Unknown Causes of various observed effects. They may be of any order of existence. We give a physical form and name to a bell but not to its tone, though in each case we know nothing but our own impressions. But we record musical sounds by a special convention. We may therefore call a certain set of qualities “Ratziel”, or describe an impression as “Saturnian” without pretending to know what anything is in itself. All we need is to know how to cast a bell that will please our ears, or how to evoke a “spirit” that will tell us things that are hidden from our intellectual faculties.
