Point name meaning:

Sù Wèn states: [The area] above the celestial pivot is governed by celestial qì; [the area] below the celestial pivot is governed by the earthly qì. The place where these qì intersect is the origin of man’s qì and the ten thousand things. This quotation shows that the junction of celestial and earthly qì in the body is the Celestial Pivot. The point name refers to the point’s location in the center of the body and to its relative importance as a juncture of celestial and earthly qì.

天枢 (tiān shū) is the ancient name of the central star in the Northern Dipper; the other six stars in that constellation rotate around it. The Sù Wèn states that the upper body has three qi’s, this is the celestial part, and is governed by celestial qì; the lower body has three qi’s and is governed by earthly qì. The three stars above and below the Celestial Pivot are representative of the three qi’s above and below ST-25.

The numerous alternate names for ST-25 provide a good sample for the study of the effects of mistranscription on acupuncture point names.

Note that the character means valley, and in the modern simplified script, it replaces meaning grain. See acupoint names: origins, meanings, and translations.
