Until there is not a shadow of self remaining, there remains the shadow of BUT in man.  Until Jesus ascended fully to the Father, he remained aware of the dualism of BUT; this is why he told Mary not to touch him.   In this moment, his awareness of BUT could be said to be transparent, almost non-existent.  If Mary had touched him, she would have caused him to descend from the purity of his transparency.

The BUT of BUT Christ liveth in me is the BUT of the bridge of going through the mind to get beyond the mind.  The Comforter of words and thoughts that support the Son of God as he travels his path of the dropping of 'self', words and thoughts that point to the BUT-less Mind of the Father.
