This is considered by many Troward's masterpiece.

FROM THE PUBLISHER: This DeVorss edition takes the liberty of helping the reader by (1) introducing paragrahing, as Troward's paragraphs are exceedingly long; (2) introducing punctuation to ease the reading and (3) closing up some words that in Troward's day were hyphenated. Also footnotes have been added to help in the translation of many foreign terms and phrases. Finally, several errors that have disserved this work for almost a century have at last been dealt with.
