G.W.F. Hegel Here is some of the spiritual tradition that was a early precursor to German idealism (quotes taken from Timothy Freke's book on Christian mystics)
"In the reality, intuitively know by the mystics, we can no longer speak of Father, Son, and Holy Spirit, nor of any creature, but only One being, that is the super-essence of all." John van Ruysbroeck
"God lies on a maternity bed giving birth to the All. God is creating this whole universe, full and entire, in this present moment." Meister Eckhart
"I have seen the One who is, and how He is the being of all creatures." Angela of Foligno
"The one work we should rightly undertake is eradication of the self. Could you completely forget yourself even for just an instant, you would be given everything." Meister Eckhart
"The world is pregnant with God." Angela of Foligno
"Simple people imagine that they should see God as if He stood there and they here. This is not so. God, and I, we are one." Meister Eckhart
"I AM can be spoken by no creature, but by God alone. I must become God and God must become me, so completely that we share the I eternally." Meister Eckhart
"Someone who is joined to the Lord is One Spirit." St. Paul
"If the only prayer you say in your whole life is 'thank you,' that would be enough." Meister Eckhart
We exist as nothing which is why Hegel speaks of positive and negative. Negative is passage, change, (whenever he uses the word negative, some change is occuring in the dialectic) while positive is philosophical determination of truth. Yin and Yang. Maybe negative is the matter and positive is the form. Hmm
