"For this reason, I withdrew myself even more from everyone, and was alone day and night" - "The Prophecies and Revelations of Saint Bridget (Birgitta) of Sweden" - Chapter 10; part II

"For this reason, I withdrew myself even more from everyone, and was alone day and night, fearing greatly, and most of all, that my mouth should say anything, or my ears hear anything against the will of my God, or that my eyes see anything alluring or harmful. I was also afraid in the silence, and very worried that I might be silent about things of which I should, instead, have spoken.

While I was worried in my heart like this, alone by myself and placing all my hope in God, an inspiration about God’s great power came over me, and I recalled how the angels and everything created serve him, and how his glory is indescribable and unlimited. While I was thus fascinated by this thought, I saw three wonderful things: I saw a star, but not the kind that shines in the sky; I saw a light, but not the kind that shines in this world; I smelled a fragrance, but not of herbs or anything else of this world. It was most delightful and truly indescribable, and it filled me up so completely that I jubilated with joy!

After this, I immediately heard a voice - but not from a human mouth - and when I heard it, I shuddered with the great fear that it might be an illusion, or a mockery by an evil spirit. But shortly after this, an angel of God appeared before me; he was like the most handsome of men, but not in the flesh as is the body of a created man, and he said to me: ‘Hail, full of grace, the Lord is with thee!’ When I heard this, I wondered what he meant and why he had come to me with such a greeting, for I knew and believed that I was unworthy of any such thing - or any good thing! However, I also knew that nothing is impossible for God, if he desires it.

Then the angel spoke again: ‘The child to be born in you is holy and will be called the Son of God. May his will be done as it pleases him.’ But, not even then did I consider myself worthy, and I did not ask the angel why, or when, this would happen. Instead, I asked him how it could be that I, an unworthy maiden, who did not know any man, should become the Mother of God. The angel answered me (as I have just said): ‘Nothing is impossible for God, for whatever he wants to do will be done.’"
