I told you you would not understand. You have not been one of the initiated or you have no soul.
Nostradamus addressed those he believed could understand his work with the Latin phrase: "Qui legent hosce versus maturè censunto, Profanum vulgus et inscium ne attrectato, Omnesque Astrologi, Blenni, Barbari procul sunto. Qui aliter facit, is ritè sacer esto." This translates to a warning that his prophecies are intended for a select few with the wisdom to interpret them, not the "profane and ignorant".
Meaning and context
This verse is found in a Latin section of Les Propheties. Nostradamus used a combination of languages and cryptic techniques to make his work difficult for the uninitiated to understand. He considered the "initiated" to be those with knowledge of subjects like astrology and classical literature, who could understand his true meaning, unlike those he saw as "fools" and "barbarians".
