If these excerpts are to be interpreted literally, yours, I think, would be the only possible meaning. But a literal interpretation is impossible, if spiritual life is not borne magically or mechanically. In my opinion, there is here a symbolical expression of the current religious feeling and knowledge, that salvation presupposes memory, becoming what we are, as Aeschylus put it, that is godly. This can not be a guess, or a momentary intuition, but certain, alive, and perfect knowledge, as is also evident by the Homeric hymn to Μνημοσύνη. Memory is not a faculty of the human organism, but a Goddess, married to Zeus and mother to the Mouses, that is Goddess-mothers of human-godly virtues. Μνημοσύνη is the fullness of Grace descending upon the awakened man, perfecting one’s familiarity with the truth. Here is the text of the Homeric hymn (in Greek):
Μνημοσύνην καλέω, Ζηνὸς σύλλεκτρον, ἄνασσαν ἣ Μούσας τέκνωσ᾽ ἱεράς, ὁσίας, λιγυφώνους ἐκτὸς ἐοῦσα κακῆς λήθης βλαψίφρονος αἰεί πάντα νόον συνέχουσα βροτῶν ψυχαῖσι σύνοικον εὐδύνατον κρατερὸν θνητῶν αὔξουσα λογισμόν ἡδυτάτη, φιλάγρυπνος ὑπομνήσκουσά τε πάντα, ὧν ἂν ἕκαστος ἀεὶ στέρνοις γνώμην κατ<ά>θηται οὔτι παρεκβαίνουσ᾽, ἐπεγείρουσα φρένα πᾶσιν ἀλλά, μάκαιρα θεά, μύσταις μνήμην ἐπέγειρ εὐιέρου τελετῆς, λήθην δ᾽ ἀπὸ τῶν<δ᾽> ἀπόπεμπε.
