A treasure chest in book form, a Vademecum ("Come with me!") through the twelve holy nights from Christmas to Epiphany. It is evident that in the present day, the path through the twelve holy nights cannot be walked in the same way as it was in the Middle Ages, due to a different state of mind and consciousness. Every contemporary individual will want to navigate the path through the twelve holy nights in a way that suits them. This book is intended to be a Vademecum for those contemporaries who do not wish to spend these special nights and days mindlessly, but rather want to use them for mystical deepening: because no other season of the soul is as favorable for this as this one (Rudolf Steiner).
