According to the spiritual-scientific research of Rudolf Steiner, the greatest spiritual event of our time is the renewal and reawakening of the human being's supersensible relationship to higher spiritual worlds. The force that brings about this development - referred to by different names in various cultural and religious traditions - is known in spiritual science, in accordance with Christian terminology, as the 'Christ Impulse'. As an outcome of new and naturally-endowed supersensible faculties, human beings are increasingly able, as an act of grace, to experience and perceive the mighty spiritual force of the Christ Impulse. Such an experience can be spoken of as a 'naturally-given initiation' - and today we increasingly hear of individual supersensible experiences of this kind. However, if we wish to take a healthy, modern approach in dealing with these 'natural' phenomena, it is necessary that we begin to comprehend them in full consciousness and with clear thought. It is this all-important bridge between the naturally-given experience of the supersensible and its conscious cognition which Ben-Aharon seeks to build in this book. As a result of such a connection, '...empirical supersensible research can investigate the different aspects of Christ's etheric becoming and appearance in a way that, both methodically and experientially, fulfils the justified cognitive and scientific requirements of our age. ' This edition features a new introductory chapter.
