Saint Teresa wrote in her 'Spiritual Testimonies' of the vision she had of Our Lady, at the chior of the Incarnation.
" ....... at the beginning of the Salve Regina, I saw the Mother of God descend with a great multitude of angels .............. She remained for the whole of the Salve, and she told me: You were indeed right in placing me here; I shall be present in the praises they give my Son, and I shall offer these praises to Him."
