Five Elements Spirit Perspective
| Spirit of the Point | Extremity of Yin is the final point on the longest meridian; from here you move to the Yin of KI-1 Bubbling Spring. You go down to the Extremity of Yin before you come up to the Bubbling Spring. It keeps the cycle turning: the end comes ahead of the beginning, a return to what is new. As the Metal point and Tonification point, it brings purity and sparkling clarity to Water, helping a person keep what is of value and let go of the rest. |
|---|---|
| Worsley | Carries us safely to the furthest extreme of ourselves, where real growth, expansion and transformation take place. Living vibrantly means never arriving at a fixed destination: we travel as far as we can into one extreme and then simply cycle on into another phase, expression and possibility. Location: At the nail point on the outer (lateral) side of the little toe. |

From Class
- BL-67 Zhiyin: Jing-well used as a release point, like a sinew treatment, to drain the ashi. (Yuen)
- Breech: moxa BL-67 (32–36 weeks); Ren-8 salt moxa: BL-67 moxa just agitates the fetus to move — not if the head is engaged; moxa Ren-8 (salt moxa if possible) to pivot downward. (Lewis)
- Jing-well indications (overview): Jing-wells open the portals and resuscitate yang: PC-9, SI-1, HT-9 for behavior change; LU-11, LI-1 throat; SP-1 stops bleeding; HT-9 tongue pain, heart attack. (Gioioso)
- Jing-well sequence in labor: BL-67 → LI-1 → ST-45 …: Only once contractions span the whole Dai: start with water (BL-67), end with wood; LI-1 opens the birth canal; ST-45 after the cervix opens. (Lewis)
