Hi Ernie—Welcome. I appreciate your 'carefully worded' reflections here.
One of the things I liked about Sperry's presentation is that he encouraged us as participants to flow between words and silence, like walking on two legs or flying with two wings.
Whether we did this well is another matter, but I found it to be a useful way of illustrating a general dynamic polarity—i.e., between words and silence or other forms of non-verbal communication/interbeing—that one need not choose between in any absolute sense.
A good writer or speaker is necessarily a good reader or listener. (I'm sure there are exceptions, but in some sense, if we look closely enough, I think it must be true.)
The love of words is curious thing, for sure. I confess to being a Word Lover, but I love the Silence just as much. And what if words leave you speechless, or a silence is pregnant with words?
I believe these are high and important arts—i.e., reading and writing, communication—which involve the whole being. "Excruciatingly difficult to embody together," you say. Truly. But embody it we must! The Poetic Bubbling of the Quantum Foam demands no less.
Glad to hear about your connection to Raimon Panikkar. A friend & occasional visitor here, @JimT, has been a student of Wayne Liquorman (a student Panikkar), and sent me a bunch of his books, which I've enjoyed—especially, No Way: A Guide for the Spiritually "Advanced," pseudo-authored by Liquorman's alter-poet-trickster-churlish-sage persona Ram Tzu. You might enjoy his un-wordy way of pointing out 'the Way'.
