Eckhart von Hochheim OP (c. 1260 – c. 1328), commonly known as Meister Eckhart[a] or Eckehart, was a German theologian, philosopher and mystic, born near Gotha, in the Landgraviate of Thuringia (now central Germany) in the Holy Roman Empire.
Here are a few of his quotes:
If the only prayer you ever say in your entire life is thank you, it will be enough.
The eye with which I see God is the same eye with which God sees me.
Every creature is a word of God.
Only the hand that erases can write the true thing.
He who would be serene and pure needs but one thing, detachment.
