|John of Ruysbroeck|
"(In the Reality unitively known by the mystic), we can speak no more of Father, Son and Holy Spirit, nor of any creature, but only one Being, which is the very substance of the Divine Persons. There were we all one before our creation, for this is our super-essence. There the godhead is in simple essence without activity.Similarly, in a description that is markedly similar to the Eastern process of negation, found in both Buddhist and Vedantist teachings, the renowned German mystic, Meister Eckhart, remarked:
[Huxley, "The Perennial Philosophy," p. 31.]
"Thou must love God as not-God, not-Spirit, not-person, not image, but as He is, a sheer, pure absolute One, sundered from all two-ness, and in whom we must eternally sink from nothingness to nothingness."
[Ibid., p. 32.]
"In the phrase used by Scotus Erigena," he notes, "God is not a what; He is a That. In other words, the Ground can be denoted as being there, but not defined as having qualities. This means that discursive knowledge about the Ground is not merely, like all inferential knowledge, a thing at one remove, or even at several removes, from the reality of immediate acquaintance; it is and, because of the very nature of our language and our standard pattern of thought, it must be paradoxical knowledge. Direct knowledge of the Ground cannot be had except by union, and union can be achieved only by the annihilation of the self-regarding ego, which is the barrier separating the 'thou' from the 'That'."
I am neither 'this' nor all attachments and forms; neither name, self-image, feelings or thoughts; nor the ego. "I am That" - the divine Ground of Being.
