Major Combinations:

• Cold abdomen:
    Huiyang Bl-35 with Lougu Sp-7
    (Wang Zhizhong, 王執中, 1220: Zhen Jiu Zi Sheng Jing, 針灸資生經, Classic of Supporting Life with Acupuncture and Moxibustion).
  
  
• Problems relating to the Fourth Level of Manifestation of the Soul, equivalent to the Anahata Chakra:
    Huiyang Bl-35 with Baihui Du-20 and Huiyin Ren-1 or Yinjiao Ren-7
    (Yuen, 2005, 3 Spirits & 7 Souls. see notes below).

Notes:

This point is indicated in problems with the Fourth Level of Manifestation of the Soul, or the Anahata chakra, concerned with the evolution of the soul, creation, "mind becoming matter" and the ability to turn ideas into actions that have consequences. This manifests in hopelessness, cynicism and inability to see reality as illusion. The other points in this set are Baihui Du-20 and Huiyin Ren-1 or Yinjiao Ren-7 (Yuen, 2005, 3 Spirits & 7 Souls).

In Sufism this level would relate to the Valley of Independence or Detachment described by Attar in the Conference of the Birds as:

"Seven oceans here in one breath turn into a pool
Seven burning globes turn here to a fire ball, the whole;
If a part or the whole system perish here
It seems that a straw is lost in the sphere ..."

Here the mystic feels free of worldly concerns as they are all simply a drop in the ocean that God.

Like the other even (Yin) sets there is one point representing Yang (Baihui Du-1), one representing Yin (Huiyin Ren-1) and one that unifies them in the lower Dan Tian (Huiyang Bl-35). This time the polarity is even more extreme but are also all Hui meeting points, suggesting their distance seeming even more extreme as their impending unification approaches.
