He was surprised at his own calm, but he did not have perfect faith in it. He felt as though something in the very depths of his being were bubbling, very softly, but persistently: welling up, seething, pressing on, but far, far away. He was in a mood as one who waits for something that must come from afar, a distant music that must draw near, little by little, singing, murmuring, frothing, rushing, roaring, and whirling down over him, catching him up he knew not how, carrying him he knew not whither, coming on as a flood, breaking as a surf, and then — But now he was calm. There was only the tremulous singing in the distance; otherwise all was peace and tranquility.

I think it had whispered to him things about himself which he did not know, things of which he had no conception till he took counsel with this great solitude - and the whisper had proved irresistibly fascinating. It echoed loudly within him because he was hollow at the core.

There are quiet places also in the mind,” he said, meditatively. “But we build bandstand and factories on them. Deliberately — to put a stop to the quietness. We don’t like the quietness. All the thoughts, all the preoccupation in my head — round and round continually.” He made a circular motion with his hands. “And the jazz bands, the music hall songs, the boys shouting the news. What’s it all for? To put an end to the quiet, to break it up and disperse it, to pretend at any cost it isn’t there. Ah, but it is, it is there, in spite of everything, at the back of everything. Lying awake at night, sometimes — not restlessly, but serenely, waiting for sleep — the quiet re-establishes itself, piece by piece; all the broken bits, all the fragments of it we’ve been so busily dispersing all day long. It re-establishes itself, an inward quiet, like this outward quiet of grass and trees. It fills one, it grows –a crystal quiet, a growing expanding crystal. It grows, it becomes more perfect; it is beautiful and terrifying, yes, terrifying, as well as beautiful. For one’s alone in the crystal and there’s no support from outside, there’s nothing external and important, nothing external and trivial to pull oneself up by or to stand up, superiorly, contemptuously, so that one can look down. There’s nothing to laugh at or feel enthusiastic about. But the quiet grows and grows. Beautifully and unbearably. And at last you are conscious of something approaching; it is almost a faint sound of footsteps. Something inexpressibly lovely and wonderful advances through the crystal, nearer, nearer. And oh, inexpressibly terrifying. For if it were to touch you, if it were to seize and engulf you, you’d die; all the regular habitual, daily part of you would die. There would be and end of bandstands and whizzing factories, and one would have to begin living arduously in the quiet, arduously n some strange unheard-of manner. Nearer, nearer come the steps; but one can’t face the advancing thing.

It echoed loudly within him because he was hollow at the core.

Tis calm indeed! so calm, that it disturbs
And vexes meditation with its strange
And extreme silentness.

He pleaded so much that he lost his voice. His bones began to fill with words.

It was mortifying to find how strong the habit of idle speech may become in one’s self. One need not always be saying something in this noisy world.

The 'voice of sanity' is getting hoarse.

Sometimes, during the lonely hours on the control deck, Bowman would listen to this radiation. He would turn up the gain until the room filled with a crackling, hissing roar; out of this background, at irregular intervals, emerged brief whistles and peeps like the cries of demented birds. It was an eerie sound, for it had nothing to do with Man; it was as lonely and meaningless as the murmur of waves on a beach, or the distant crash of thunder beyond the horizon.

His voice was low, charged with unspeakable adjectives.

On the thought a blessed silence came, an empty clarity. He took it a first for utter desolation, but desolation was a type of free fall, perpetual and without ground below. This was stillness: balanced, solid, weirdly serene. No momentum to it at all, forward or backwards or sideways.

He lay drained of tension, not moving, and content to be so. The oddly stretched moment was like a bite of eternity, eaten on the run. Was this quiet place inside something new-grown, or had he just never stumbled upon it before? How could so vast a thing lay undiscovered for so long? His breathing slowed and deepened.

At this table, a loud voice was just a man venting his stress. A quiet one was far more dangerous.

and his voice came from him in a whisper,

Once the quietness arrived, it stayed and spread in Estha. It reached out of his head and enfolded him in its swampy arms. It rocked him to the rhythm of an ancient, fetal heartbeat. It sent its stealthy, suckered tentacles inching along the insides of his skull, hoovering the knolls and dells of his memory; dislodging old sentences, whisking them off the tip of his tongue. It stripped his thoughts of the words that described them and left them pared and naked. Unspeakable. Numb. And to an observer therefore, perhaps barely there. Slowly, over the years, Estha withdrew from the world. He grew accustomed to the uneasy octopus that lived inside him and squirted its inky tranquilizer on his past. Gradually the reason for his silence was hidden away, entombed somewhere deep in the soothing folds of the fact of it.
