"because of the seven dolours which transpierced her own heart." (U13.445)
The seven dolours which transpierced Mary's own heart took place 1) at the prophecy of Simeon, 2) at the flight into Egypt, 3) having lost the child Jesus in Jerusalem 4) meeting Jesus on his way to Calvary, 5) standing at the foot of His Cross, 6) when He is taken from the Cross, 7) at His burial. The seven dolours are the attributes of Our Lady of Sorrows (Feasts around Easter, and September 15). They are the principal devotion of the Servite Order, founded in the 13c.
