Yesterday we concluded by outlining the three methods of occult development: the Eastern, the Christian and the Rosicrucian. Today we will begin by going more closely into the details which distinguish these three paths. But first I should say that no occult school sees in its teaching and requirements anything like a moral law valid for all mankind. The requirements apply only to those who deliberately choose to devote themselves to a particular occult training. You can, for instance, be a very good Christian and fulfil everything that the Christian religion prescribes for the laity without undergoing a Christian occult training. It goes without saying that you can be a good man and come to a form of the higher life without any occult training.
