Charubel's image for this degree is a single overwhelming natural feature: a waterfall of stupendous size, offered without any human figure to witness it or any further action attached. The word stupendous does real work here, insisting on scale large enough to exceed ordinary description, a force of nature meant to be felt as excessive rather than merely large.
Water falling under its own weight, continuously and without effort, is a fitting image for a sign whose core business is momentum, force that does not need to be generated because it is already built into the nature of the thing itself. Nothing in the picture suggests the waterfall could be stopped or redirected; it simply continues, degree after degree, the way Sagittarius itself tends to keep moving outward once it has started.
The wording now attached to this degree in general circulation follows Dane Rudhyar's 1973 restatement in An Astrological Mandala, building on the 1925 material Jones and Wheeler produced; that copyrighted text is not reproduced here. Within Mercury's decan and Jupiter's term, quickness and expansiveness combine in a picture of continuous, unforced power, an early statement of how much this sign trusts sheer momentum over deliberate control.
