The invocation is, as one sees, almost inexhaustible in light and fire attributes, and can be likened in its extravagance only to the synonymous attributes of love of the mystic of the Middle Ages. Among the innumerable texts which might be used as an illustration of this, I select a passage from the writings of Mechthild von Magdeburg (1212–1277): “O Lord, love me excessively and love me often and long; the oftener you love me, so much the purer do I become; the more excessively you love me, the more beautiful I become; the longer you love me, the more holy will I become here upon earth.” God answered: “That I love you often, that I have from my nature, for I myself am love. That I love you excessively, that I have from my desire, for I too desire that men love me excessively. That I love you long, that I have from my everlastingness, for I am without end.”[131] The religious regression makes use indeed of the parent image without, however, consciously making it an object of transference, for the incest horror[132] forbids that. It remains rather as a synonym, for example, of the father or of God, or of the more or less personified symbol of the sun and fire.[133] Sun and fire—that is to say, the fructifying strength and heat—are attributes of the libido. In Mysticism the inwardly perceived, divine vision is often merely sun or light, and is very little, or not at all, personified. In the Mithraic liturgy there is found, for example, a significant quotation: Ἡ δὲ πορεία τῶν ὁρωμένων θεῶν διὰ τοῦ δίσκου, πατρός μου, θεοῦ φανήσεται.[134] Hildegarde von Bingen (1100–1178) expresses herself in the following manner:[135] “But the light I see is not local, but far off, and brighter than the cloud which supports the sun. I can in no way know the form of this light since I cannot entirely see the sun’s disc. But within this light I see at times, and infrequently, another light which is called by me the living light, but when and in what manner I see this I do not know how to say, and when I see it all weariness and need is lifted from me, then too, I feel like a simple girl and not like an old woman.” Symeon, the New Theologian (970–1040), says the following:
