Why can't we talk about the absolute beyond all knowing?

The Buddha was rather clear about it, elevating it from the Vedas, and even avoiding the doctrine of emptiness as a way of understanding it.
Fast forward to today. How many teachers and philosophers overlook, forget, or are unable to make that final assertion that it cannot be asserted by any words, thoughts, or concepts? When they do, is it based on their direct experience, a memory of a direct experience, or just because that is what they have been told? Is an appreciation of unity and a liberated mind enough to say that the absolute stillness is the nameless "basis" for one's beingness?
For me it's like a "falling away" of everything. I can still the mind and have it right now. It cab be experienced during a pause in the conversation. The directness of it "appears" to come and go with the intervening of the mind's activities, yet when the mind and even pure awareness itself falls away, it is :known" that "it" was always "here." What else can be said? It's not magical, or profound, or not this-not that, or realizable, or personal, or teachable, or describable. It is as the better teachers say, that which one can be directed or lead to to a point and no further, and then still beyond. Far, far far beyond, as the Gospel of Mary Magdalene put it. Others have put it in ways that convey a sense that they have truly "experienced" it directly. It's really a form of false teaching to put it into any words without asserting vigorously each and every time that it is wordless, imageless, without any conception or place to have a foothold or support by the mind (as the Lankavtara put it - ten stages of Bodhisatvahood, the final 3 being deepening stages of enlightenment, buddha realization being beyond the 10th. Isn't that what is meant by attaining Buddahood? Isn't that why so many recognized "awakened" teachers defer to the Buddha as being bigger/deeper than they? Because they know in some sense that they have not or cannot fall away enough to experience the wordless, utter stillness that is beyond any concept of absolute reality itself.
