The Grail Message »In the Light of Truth« was newly composed by Abd-ru-shin (Oskar Ernst Bernhardt) in the years 1940 and 1941. The reasons for this are shown in detail in the Internet at
http://www.die-gralsbewegung.org/die-gralsbotschaft-der-weg-von-der-urfassung-zum-manuskript-letzter-hand/ 

The Manuscript for this new composition of the Grail Message was used for the post-war editions of the Grail Message »Edition of the Last Hand« and the book »Admonitions« which is not available in bookshops.

The Manuscript of the Grail Message »Edition of the Last Hand« includes a table of contents. In this, Abd-ru-shin has bound and fixed the sequence and selection of His lectures for the new composition in a Complete Edition.
According to this, the Grail Message should begin in the future with those 22 lectures which are today contained in the book »Admonitions« and is not available in bookshops.

These 22 lectures are not published in the Grail Message »Edition of the Last Hand«, due to unauthorised considerations by those responsible for it, contrary to the precept of Abd-ru-shin! Instead these 22 lectures were published in the book »Admonitions«, which is not available in a bookshop or through the »Stiftung Gralsbotschaft«.

How momentous this decision has been is shown at length in the »Calls from the Primordial 2013-2017«:
»You have recognised the Word, but you do not hear the Call«
