The Entrance of the Theotokos to the Temple (source)

  
Today, the All-Spotless Virgin is led to the Temple to become the dwelling-place of God, the King of All, Who is the nourishment of our life. Today, the most pure Holy One, as a three year old calf, enters the Holy of Holies. Let us cry out to her like the Angel [Gabriel]: Rejoice, O only blessed one among women.
