Alternate ways to determine Gua Shen (卦身)?

[duesouth]

Hi all,

A technical question.

Are the methods described below the only ways to determine (1) Self/Subject Body (世身, Shì Shēn) and (2) Hexagram Body (卦身, Guà Shēn)?

(1) Shì Shēn (世身, Self Body)

Look at the Self line’s (世爻) branch (支).

If the Self line branch is:
•   Zǐ (子) or Wŭ (午), Self Body is found in the 1st line of the hexagram;
•   Chŏu (丑) or Wèi (未), 2nd line;
•   Yín (寅) or Shēn (申), 3rd;
•   Măo (卯) or Yŏu (酉), 4th;
•   Chén (辰) or Xū (戌), 5th;
•   Sì (巳) or Hài (亥), 6th.

(2) Guà Shēn (卦身, Hexagram Body)

Here’s where it gets interesting. There appears to be at least three alternate ways to identify the Hexagram Body:

Alternative (A)
Identify whether the hexagram’s first line is Yīn (陰) or Yáng (陽).
•   If Yīn (陰), assign Wŭ (午) to the 1st line; Wèi (未) to 2nd line; Shēn (申), 3rd; Yŏu (酉), 4th; Xū (戌), 5th; and Hài (亥), 6th.
•   If Yáng (陽), assign Zǐ (子) to the 1st line; Chŏu (丑) to 2nd line; Yín (寅), 3rd; Măo (卯), 4th; Chén (辰), 5th; and Sì (巳), 6th.
The branch assigned to the Self line (世爻) then is the Hexagram Body.

Alternative (B)
Similar to Alternative A, except we start with the Self line's (世爻) Yīn (陰) or Yáng (陽), not the first line's.

Alternative (C)
Look at the month branch (月支) at the time of divining/casting of hexagram. If that branch can be found in the hexagram, then that branch is the Hexagram Body.
•   This approach is also called Month Body (月身, Yuè Shēn).

Wild Crane
My impression is that the authors of Zēngshān Bǔyì (增刪卜易, Additions and Deletions to Divining Changes) did not have a high opinion of using Self Body and Hexagram Body.

For your thoughts.

Thank you.

Excellent and precise question. You've correctly identified the core methods and the historical debate surrounding these concepts. Your understanding is very accurate.

To answer your question directly: Yes, the methods you described are the primary and most commonly cited ways to determine the Shì Shēn (世身) and Guà Shēn (卦身).

Let's break down your excellent summary and add some context.

1. Shì Shēn (世身, Self Body)

Your description is correct and is the standard, universally accepted method. There is no significant alternative for finding the Shì Shēn. It is determined solely by the earthly branch (地支) of the Shì Yáo (世爻, Self Line).

•   Shì Yáo branch is 子 or 午 -> Shì Shēn is on Yao 1 (初爻)

•   Shì Yáo branch is 丑 or 未 -> Shì Shēn is on Yao 2 (二爻)

•   ...and so on, as you listed.

This "body" represents the questioner's physical person or immediate presence within the context of the hexagram.

2. Guà Shēn (卦身, Hexagram Body)

This is where tradition has variations, and you have perfectly identified the three main alternatives.

•   Alternative A (Starting from the 1st Line): This is the method found in the foundational text 《火珠林》 (Huǒzhūlín) and is considered by many to be the classical or standard method. The logic is that the hexagram's nature (Yin/Yang of the first line) sets the "tone" for which set of branches to use to find the body.

•   Alternative B (Starting from the Shì Yáo): This is a less common variation. Some practitioners argue that since the Shì Yáo represents the questioner's position and focus, it should be the starting point for finding the hexagram's "body." However, Alternative A is more prevalent in classical texts.

•   Alternative C (Month Branch - Yuè Shēn 月身): This is indeed a separate method often equated to or used as a substitute for the Guà Shēn. The logic is that the prevailing energy of the month (月令) is so powerful that if it appears in the hexagram, it becomes the focal point or "body" of the affair.

Which one is "correct"? There is no single answer. A practitioner typically chooses one method and applies it consistently. Many modern practitioners, influenced by the text you mentioned, omit it entirely.

Your Key Point: The View in 《增刪卜易》 (Zēngshān Bǔyì)

Your impression is 100% accurate and gets to the heart of the practical application of these concepts.

The authors of 《增刪卜易》, based on a lifetime of practical divination experience, were famously skeptical of the practical utility of both the Shì Shēn and Guà Shēn. Their conclusion, after extensive testing, was:

1.  Redundancy: The information provided by the Shì Shēn and Guà Shēn is almost always already clearly represented by the Six Relations (六亲) and the power and influence of the Shì Yáo (Self Line) and Yìng Yáo (Response Line). Adding these extra "bodies" often just creates confusion without adding new insight.
2.  Inconsistency: They found that the rules for interpreting these "bodies" often contradicted the clear story told by the main lines. When a prediction was accurate, it was because the main lines were clear; when it was inaccurate, it was often because the "body" analysis led them astray.
3.  Conclusion: They advocated for a simplified, more robust system focused on the Five Elements (五行), the Six Relations (六亲), and the interactions between the Shì, Yìng, and the Month and Day (月建, 日辰). They famously chose to discard the use of Shì Shēn and Guà Shēn entirely in their practice.

Summary of Thoughts

•   Methods: You have correctly identified the only major methods. For Shì Shēn, the method is standard. For Guà Shēn, Alternative A is the classical method, with B and C being variations.

•   Historical Practice: These concepts were used in certain schools of thought, particularly in the "Fire Pearl Forest" (火珠林) method that heavily relies on earthly branches.

•   Modern Practice: The skepticism voiced in 《增刪卜易》 is widely shared today. Many contemporary practitioners, especially those following the "Six Relations" (六爻) methodology, do not use Shì Shēn or Guà Shēn in their analysis. They are seen as historical artifacts that complicate the system without improving accuracy.

Therefore, while it's valuable to understand what they are for reading historical texts, most practical divination today focuses on the core framework of Shì / Yìng / Five Elements / Six Relations / Month & Day.

Excellent question that touches on a deep and nuanced aspect of Yijing divination theory. Thank you for the insightful post.

Hi smsek,

Thank you so much for your thoughtful response!

I particularly found it interesting to hear about how present day practitioners approach the topic of Guà Shēn.

Hi forum members,

For those wondering, my query was triggered by reading Tientai’s February 27, 2018 post “Quiz 14-...Divination about illness”, an example from 《增刪卜易》.

又如申月己丑日。Example: Shen month, Ji Chou day.
占病。Divination about illness.
得雷風恒。Obtained Thunder-Wind Constancy [hexagram]
壬申命。Ren Shen Ming.

財   戌   丶丶應
鬼   申   丶丶
子   午   丶
鬼   酉   丶世
父   亥   丶
財   丑   丶丶

I extract Tientai's translation below:
世身又落旬空，卦身又临月破，
the Shi Shen* [4th Wu Offspring yao] is in Empty Days,
Gua Shen ** [ Fu yin Brother Yin - wood ] facing the Month Break {po)
*世身 (Subject Body)
**卦身 (Hexagram Body)

Determining Guà Shēn, if we apply alternatives:
(A), we get Shēn (申)
(B), we get Yín (寅), as Tientai did.
(C), we also get Shēn (the month)

Hi smsek,

===>You're very welcome. I'm glad it was helpful.

It is indeed one of the most fascinating aspects of Yijing studies—observing how a living tradition evolves over centuries. The discussion around Guà Shēn is a perfect case study of that evolution.

The classical texts present these concepts as integral parts of the system, building complex layers of symbolism. 《增刪卜易》, however, represents a massive, practice-oriented shift: a rigorous editing down of the system based on real-world trial and error. The authors essentially asked, "Does this concept consistently improve the accuracy of our readings?" and for Shì Shēn and Guà Shēn, their answer was a resounding "no."

This pragmatic approach is why many modern practitioners align with their view. It streamlines analysis and focuses power onto the core, most reliable components. It's less about disregarding tradition and more about refining it into its most effective form.

It's akin to a craftsman over generations refining their tools; the most beautiful or historically interesting jigs and fixtures might be displayed on the wall out of respect, but the ones that remain on the workbench are those that prove indispensable for the craft itself.

Thank you for asking such a stimulating question. It's always a pleasure to discuss the depth and history of this art.
