Emptiness

Keep this in mind: to be full of things is to empty of God, while to be empty of things is to be full of God.

Therefore, if a heart is to be ready for Him, it must be emptied out to nothingness. So too, a disinterested heart, reduced to nothingness, is the optimum, the condition of maximum sensitivity.

When he wrote this, Meister Eckhart went on to suggest that this is what Jesus meant when he said: "Blessed are the poor in spirit for theirs is the kingdom of heaven."
