According to the Gospels, Mary sat at the foot of the Cross, I think that all parents who watch their children suffer needlessly know her sorrow. Turn to her to help us understand suffering as we turn to Jesus to bind our suffering to his for the salvation of the world.
Jesus' father and mother were amazed at what was said about him; and Simeon blessed them and said to Mary his mother,
"Behold, this child is destined
for the fall and rise of many in Israel,
and to be a sign that will be contradicted
and you yourself a sword will pierce
so that the thoughts of many hearts may be revealed."
-- Luke 2:33-35
