The Unicorn is speech. Man, rule thy Speech! How else shalt thou master the Son, and answer the Magician at the right hand gateway of the Crown?
Here are practices. Each may last for a week or more.
Avoid using some common word, such as "and" or "the" or "but"; use a paraphrase.
Avoid using some letter of the alphabet, such as "t", or "s", or "m"; use a paraphrase.
Avoid using the pronouns and adjectives of the first person; use a paraphrase.
Of thine own ingenium devise others.
On each occasion that thou art betrayed into saying that thou art sworn to avoid, cut thyself sharply upon the wrist or forearm with a razor; even as thou shouldst beat a disobedient dog. Feareth not the Unicorn the claws and teeth of the Lion?
Thine arm then serveth thee both for a warning and for a record. Thou shalt write down thy daily progress in these practices, until thou art perfectly vigilant at all times over the least word that slippeth from thy tongue.
Thus bind thyself, and thou shalt be for ever free.
