The term loneliness was my term. Don't make too much out of it. It is not a rule of Catholic mysticism and I did not associate it with God. I only referred to it as part of the purging process on a person's personal path. Another person may use a different term.
Again, you are comparing exterior experiences to my discussion of interior changes. We are not talking about the same thing. kosta understands my intent. I don't know how to phrase this any other way.
Of course, the "hard evidence" of interior transformation is in external changes -- so in such discussions the internal and external are usually inextricably tied together.
We still may be completely talking at cross-purposes, though. I'll take your word for it that we are. I may be so immersed in the Orthodox way of thinking and talking about the spiritual life that I may find it difficult to follow what is being said about Catholic approaches.
