The overall theme of the three books is the message of Matthew 25:6, "See, / the Bridgegroom cometh, / go out / to meet him", which involves a four-step experience in each of the three "lives".
Our readers see the books the same way that their first readers did decades or a hundred or more years ago. Books from that period are often spoiled by imperfections that did not exist in the original.
The edition is preceded by a short Introduction describing Ruusbroec's life and doctrine and summarising the dating and context of the various treatises and letters, and is followed by a source apparatus and index of sources.
