Szekely later said that he recognized several fragments in these that were either similar, or identical, to various passages from the Old and New Testaments, the Dead Sea Scrolls, and the Avesta and thus he relied on available English editions of those works to produce the style of language used in his translations. Book 1, which he said constituted an eighth of the material, was published in 1936. He published more material in following years, including Books 2 and 3 in 1974, which with Book 1, he said, make up a third of the material. With the 1974 edition, he also included what he said was the complete original Hebrew text from which he translated Book 1.
