Meeting the Buddhas has been translated into German. As it’s a big book, the publishers decided to break it up into three volumes, as has now been done in English as well:
Das Weise Herz der Buddhas (Essen: Do Evolution 1999) contains the introductory part and the chapters on the mandala of the Five Buddhas.
Zum Wohl Aller Wesen (Essen: Do Evolution 2001) contains all the material about the Bodhisattvas.
Flammen der Verwandlung (Essen: Do Evolution 2003) is the last section, on the tantric deities.
