The only way to deeply understand the Bible is to have some knowledge of the original languages: Hebrew and Greek, in combination with the sciences that helped create scripture: kabbalah and alchemy. However, this knowledge will not benefit if we do not deeply meditate upon what we read. When any of these parameters are lacking, we will have superficial and impractical understandings. As for an alternative Bible with gnostic commentary, such a translation would be too big as to be impossible, evidenced by one lecturer on the Gnostic Teachings Podcast who has been lecturing (for years) solely on the first verse of Genesis. Since this knowledge is truly universal, it has no limit and cannot be condensed into a book.
