Magic of Oz
Magic... Lots of magic action in this book with one anomaly. All the other magic takes spells, rites, rituals, preloaded coded calls, suffusions, infusions and a lot of smoke and mirrors. And then there's the one word...
"By its means, it was the simplest thing in the world to transform anyone into beast, bird or fish, or anything else, and back again, once you know how to pronounce the mystical word: "Pyrzqxgl"
If I'm correct about the pronunciation of that, it is the English loan word "puzzle" pronounced with a really thick Gaelic accent so that it could be spelled "puzhel", with the "zh" trilled and the final "l" unvoiced with a lot of breath. Sort of like saying "guess the secret word" and the secret word turns out to be "secret word".
But Theosophy does have a single word which is supposed to transform. In the Great Outer World it is supposed to transform the "Understanding" mind of the speaker, through a certain kind of meditation on its meaning, into the mind of a Paragnostic.
This is a matter of Chinese metaphysics. Firstly consider the Theosophic causative sequence of Magic. The colors are North to Below to East to Center to West to Above to South as always and the sequence is in the order of Recusion.
In the operation of magic the flow around the center is clockwise. From the Purple Specific Absence at the North, definitions are spelled at the Orange East by name and symbolism, operate by the action-by-means-of-non-action of the South Red and become apparent at the West Blue by always-has-been-so and remain as a supportative Purple Specific Absence at the North. The constraints of time and place are the responses of the Green Compliance Below guided by the taboos and particulars of the Yellow Limits Above. The magician operates in the Clear Center and defines a very general result leaving the fine details to the magic.
It has been a more or less understood concept since the 1940s that magic cannot be magical. That its substratum must be scientifically mundane. Fantasy fiction of the late 50s and early 60s carried that out by having magic be actually psionic powers which were guided and reinforced by the spells, potions etc but the spells etc were merely symbolic.
In the late 60s magic as magic made somewhat of a comeback but the opinion remains that this is an essentially non magical world.
Theosophy in its take on Chinese metaphysics takes quite the opposite view. It says that the world is entirely magical and the progress of Evolution which is - Recursion generating Relationship generating Time and Space generating Energy and Matter generating Life and Awareness generating Knowledge generating Understanding generating Paragnosis - is entirely magical and extremely stable. Thus it merely appears as non magical because it is so dependable and normal.
Faerie being topsy turvy to Mundania, what is implicit in Mundania is explicit in Faerie. So the word that transforms the mind in Mundania transforms the body in Faerie. That word can be called a "puzzle" but is made up of the consonants and vowels that represent the meanings in sequence of Recusion.
