From a letter written by the French nun St. Margaret Mary: 

This divine heart (Sacred Heart of Jesus) is an abyss of all blessings, and into it the poor should submerge all their needs. It is an abyss of joy in which all of us can immerse our sorrows. It is an abyss of lowliness to counteract our foolishness, an abyss of mercy for the wretched, an abyss of love to meet our every need.
