In Mary, God "dwelt on earth and made his imprint on it"

Michael Psellos (1018-1078 or 79) was a Byzantine Greek monk who gave a truly splendid ascetic and virginal image of Mary in her luminous path of ascent to God.

"The Virgin was truly a virgin, she kept the thoughts of her spirit wholly pure, and remained in her body like a sun with intelligible graces, illuminating and ennobling it (...).

Unique among all human souls, her soul, very similar to God, shone in her immaculate body like a celestial splendor; and she was not so much contained by her body, as she contained it, preserved it, and communicated to it her own radiance.

Her spirit was truly filled with God, although she was not divine, and her body was so united to her spirit that she was completely enclosed in God.

And God lived with her body; he dwelt on this earth and made his imprint on it, but, if it is permitted to speak in this way, she was not far from the inaccessible Trinity, and rose above the seraphim; even before she conceived [the Word made flesh], she saw God and conceived him, bore him, gave birth to him in an ineffable way through contemplation, as she later did substantially."
