Guido Judica-Cordiglia was a 20th-century Italian esotericist who was deeply interested in the I Ching and its applications. He spent many years studying the text and developed his own unique interpretation, which he published in a book titled "I Ching" (also known as "The Book of Changes"). Judica-Cordiglia's translation and interpretation of the I Ching is considered to be one of the most insightful and accurate versions of the text.
