The Most Holy Theotokos the "Softener of Evil Hearts" is also called the "Prophecy of Simeon" (or "Simeon's Prophecy") since Righteous Simeon said to the Most Holy Virgin, upon the presentation of Our Lord in the temple:
"Behold, this child is set for the falling and rising again of many in Israel, and for a sin which shall be spoken against. Yea, a sword shall pierce through thy own soul also, that the thoughts of many hearts may be revealed."
The Theotokos is depicted in this icon with her heart pierced by seven swords; a symbolic number indicating the the fullness and boundless sorrow, pain and "sickness of heart" that would have been experienced by the Mother of God at His crucifixion. Three of the swords enter her heart from the left, three swords enter from the right and one sword from underneath.
The “Softener of Evil Hearts” icon is commemorated on the Sunday of All Saints.
