I like the idea of "deep...feelings"
but I would want to translate "devout" as intimate.
So for me it would be "deep intimate feelings..."
For sure, life is becoming more intimate for me;
So here is my rewrite on that sentence of Oliver's
I'm not sure how the oak tree is intimate but the oak tree probably understands what I mean.
As I think about it, maybe it is related to being more rooted, more grounded...to the things that matter.
Oh well, bows to the oak tree, simplicity and intimacy!
