Intellectual understanding is really not understanding at all; it is only a series of words, and we think we understand those words and the content of those words, and we seem to think we understand the idea intellectually. But what you hear is unrelated to daily action, to a total limit, and communion is only possible when there is a direct relationship: communication then becomes much more interesting, much more vital, more significant, meaningful. https://jkrishnamurti.org/content/being-alone-means-being-innocent-0
The ground - nameless, silence, call it what you like. It is there. And the mind wants to capture "that", to have relationship with it. Sorry, you can't. That's all!
