The "Ground" ( Grund ) is the central motif in Eckhart's thought, serving as the bridge between the divine and the human.
"God" refers to the Trinity (Father, Son, Holy Spirit) as he relates to creation and human activity.
One of Eckhart’s most radical ideas is the distinction between the "God" of religion and the "Godhead".
A person must become "poor" in spirit, meaning they must be free of all "this and that"—including their own will and even their ideas about God.
Eckhart describes this state using the "Eye" metaphor: "The eye with which I see God is the same eye with which God sees me". It suggests a shared consciousness rather than a relationship between two separate beings. 3. Gelassenheit (Detachment or Releasement)
