This work aims to address the evolutionary path of man in connection with the higher worlds and the kingdoms of nature. Most of us will already have developed some ideas about this subject and some of the things we’re going to discuss are likely to be difficult to integrate into our accustomed way of thinking. Faced with new concepts we must try to maintain an appropriate attitude which is certainly not that of easy credulity. Indeed it is generally unwise if not dangerous to have blind faith in what someone says if you cannot verify it. However, given the inherent difficulty in directly verifying what we will discuss we ask for an attitude of openness. Such an attitude enables an intellectual evaluation, but it is also open to another and deeper hearing within our soul. It is not only our brain that will guide us to decide whether things heard or read are true, but it will be the forces of our soul, tonight, tomorrow or in the following days that will tell us whether what we have taken in is true for us.
