“In the same manner the voice executes its movements in concentric circles; but while in the case of water the circles move horizontally on a plane surface, the voice not only proceeds horizontally, but also ascends vertically by regular stages. Therefore, as in the case of the waves formed in the water, so it is in the case of the voice: the first wave, when there is no obstruction to interrupt it, does not break up the second or the following waves, but they all reach the ears of the lowest and highest spectators without an echo.”

“Voice is a flowing breath of air, perceptible to the hearing by contact. It moves in an endless number of circular rounds, like the innumerably increasing circular waves which appear when a stone is thrown into smooth water, and which keep on spreading indefinitely from the centre unless interrupted by narrow limits, or by some obstruction which prevents such waves from reaching their end in due formation. When they are interrupted by obstructions, the first waves, flowing back, break up the formation of those which follow.”

Vitruvius book De architectura

Alternate translation: The voice is a flowing breath, made sensible to the organ of hearing by the movements it produces in the air. It is propagated in infinite numbers of circular zones, exactly as when a stone is thrown into a pool of standing water countless circular undulations are generated therein, which, increasing as they recede from the center, spread out over a great distance, unless the narrowness of the locality or some obstacle prevent their reaching their termination; for the first line or waves, when impeded by obstructions, throw by their backward swell the succeeding circular lines of waves into confusion.

“So, when a pebble breaks the surface of a motionless pool, in its first movements it forms tiny rings; and next, while the water glints and shimmers under the growing force, it swells the number of the circles over the rounding pond, until at last one extended circle reaches with wide-spreading compass from bank to bank.”
Sic, ubi perrupit stagnantem calculus undam, exiguos format per prima volumina gyros, mox tremulum uibrans motu gliscente liquorem multiplicat crebros sinuati gurgitis orbes, donec postremo laxatis circulus oris contingat geminas patulo curuamine ripas.

Compare:
As on the smooth expanse of crystal lakes
The sinking stone at first a circle makes;
The trembling surface, by the motion stirred,
Spreads in a second circle, then a third;
Wide, and more wide, the floating rings advance,
Fill all the watery plain, and to the margin dance.
Alexander Pope, Temple of Fame, lines 436–441
As the small pebble stirs the peaceful lake:
The centre moved, a circle straight succeeds,
Another still, and still another spreads.

Context: It is not good for ordinary people to say, "I am He." The waves belong to the water. Does the water belong to the waves?
The upshot of the whole thing is that, no matter what path you follow, yoga is impossible unless the mind becomes quiet. The mind of a yogi is under his control; he is not under the control of his mind.
