主题：Diarmaid Macculloch：基督教简史 -- 万年看客

Eckhart, writing in vigorous and multi-layered German, introduced the idea that after abstracting the particular 'this' or 'that' and achieving 'detachment', Gelassenheit, the soul can meet God in the 'ground', Grunt, of all reality. There she can achieve an inseparable union with the divine, 'the unplumbed depth of God [which] has no name': 'Life can never be perfected till it returns to its productive source where life is one being that the soul receives when she dies right down to the "ground", that we may live in that life where there is one being.'
