It is a difficult task, my brothers, that lies before us this morning. In the two preceding lectures I have been dealing with the life of men in the world, and pointing out to you how in this ordinary life men might gradually prepare themselves for the higher stages of evolution; how they might gradually train themselves for swifter progress, for swifter advance. But today we have to go outside the life of man in the ordinary sense of the term-not so far as the outer appearance is concerned, but so far as the reality of the inner life is to be studied. For the stages of human progress that we are now to deal with are distinct and definite stages, which lead men out of the life of the world into the life of the higher regions; out of the ordinary humanity into a humanity which is divine. And inasmuch, therefore, as it must take us more outside common experience, the task is, as I say, more difficult, both for you who hear it and for myself who speak. For in these higher matters higher faculties must needs be brought into play; and they best will be able to follow this lofty teaching who, at least, have tried to some extent that purification of life and building of character to which our last two mornings have been devoted in thought.
