I have always loved this feast which used to be on May 31, my birthday, but was changed to the 22nd of August when the Feast of the Immaculate Heart of Mary was transferred to the day after the Feast of the Sacred Heart.
Th entrance antiphon: "At your right stands the queen in robes of gold, finely arrayed."
The Collect asks that we may, through Mary's intercession, attain heaven.
It is a day to go to Mary and thank her for all she has done and is doing for each of us. She sees what we need. Just as she saw the lack of wine at the wedding feast, she sees what we lack and tells Jesus about it and then says to each of us, "Do whatsoever He tells you." This requires us to listen to Jesus in our hearts.
