A language has to come from some intelligent source and have some purpose its trying to accomplish or what's the point? There's a chapter in A New Model of the Universe in which he wrote about his actual contact with that Other, which spoke in hieroglyphs and which conveyed information in what seems to me to have been a wordless language. He obviously felt he was listened to and sometimes got answers:
"I did not obtain particularly new facts through my experiments, but I got many thoughts. When I saw that my first aim, i.e., objective magic, remained unattainable, I began to think that the artificial creation of mystical states might become the beginning of a new method in psychology. This aim would have been attained if I had found it possible to change my state of consciousness while at the same time retaining full power of observation. This proved to be impossible to the full extent. The state of consciousness changed, but I could not control the change, could never say for certain in what the experiment would result, and even could not always observe; ideas followed upon one another and vanished too quickly. I had to recognise that though my experiments had established many possibilities, they did not give material for exact conclusions. The fundamental questions as to the relation of subjective magic to objective magic and to mysticism remained without decisive answers.
But after my experiments I began to understand many things differently. I began to understand that many philosophical and metaphysical speculations, entirely different in theme, form, and terminology, might in actual fact have been attempts to express precisely that which I came to know, and which I have tried to describe. I understood that behind many of the systems of the study of the world and man there might lie experiences and sensations very similar to my own, perhaps identical with them. I understood that for centuries and thousands of years human thought has been circling around something that it has never succeeded in expressing.
In any case my experiments established for me with indisputable clarity the possibility of coming into contact with the real world that lies behind the wavering mirage of the visible world. I saw that knowledge of the real world was possible but, as became clearer and clearer to me during my experiments, it required a different approach and a different preparation.
Putting together all that I had read and heard of, I could not but see that many before me had come to the same result, and many, most probably, had gone much further than I. But all of them had always been inevitably confronted with the same difficulty, namely the impossibility of conveying in the language of the dead (world, my addition) the impressions of the living world. All of them except those who knew another approach.... I came to the conclusion that without the help of those who know another approach it is impossible to do anything. "
I'm not sure any experiments such as Ouspensky devised are necessary and a physically present teacher may not be necessary, but another approach to getting information is necessary. The psychological sense as a new mindset in Freud's writings is the same form that created the Greek mythologies and even prior to their era. I suggest reading Norman O. Brown's Life Against Death, because in that book he described what I've experienced that the unconscious becomes conscious by connecting, being reflected by some event in the exterior world. This is just the beginning however, recognizing that a hidden world begins to 'speak' through those events.
That's my opinion although learning does begin with the language of the visible world. I grew up hearing the adults I knew say that 'life is a school and we are the students' often enough that the words took root. They were stabilizers when my mind changed my thought was different in fact I'd been 'thought' less basically until this point that changed every aspect of what is outside my body: everything and every thing .
