Vision While Gazing Upon a Crucifix

The welling of blood from Christ’s wounds – from His million tiny shreds of scourged flesh, from the thousand thorn marks on His head, to the bruised tear on His shoulder where He carried His cross, to the five Great Wounds of nail and spear – all that blood, welling up, forming an enormous single drop of Divine blood at his feet, which falls to the ground, splashing over the whole of the world.

That is the emblem of Divine Mercy.
