"The appearance of an archetypal image will draw the individual's attention to its general human quality or to the idea underlying it. He will become aware of new, previously unrecognized possibilities and through them will experience a fresh influx of energy; for the archetypes possess a numinous quality and function as a hidden source of energy. When a myth is enacted in a ritual performance or, in more general, simpler and profaner fashion, when a fairy-tale is told, the healing factor within it acts on whoever has taken an interest in it and allowed himself to be moved by it in such a way that through this participation he will be brought into connection with an archetypal form of the situation and by this means enabled to put himself 'into order.'
In its rudiments the Grail legend is of a similar type. However, it is distinguished from an ordinary fairy-tale by the fact that it is not anonymous - at least not in the form which it has come down to us - but has been shaped by specific poets. It therefore contains archetypal features in the foregoing sense of the word, but it is also the product of a particular age and attitude of mind. For this reason it allows us a glimpse into the specific mentality of the Middle Ages and thus touches upon problems of the Christian aeon which are psychologically important for the present day."
