Xuan Kong Da Gua Spell Circle

Xuan Kong Da Gua (玄空大卦) or XKDG in short uses a series of hexagram to invoke certain energy. Simply put, each hexagram has a specific set of numberser and to invoke these energy, one needs to connect the dots — “a number game”.


甲癸申,(贪狼)1: Opportunity and Nobleman
坤壬乙,(巨门)2: Real Estate Wealth
子卯未,(禄存)3: Competition and Risk Taking
戌乾巳,(文曲)4: Academic Pursuit and Relationship
辰巽亥,(武曲)6: Corporate Governance and Authority
艮丙辛,(破军)7: Public Speaking and Communication
寅庚丁,(左辅)8: Cashflow and Career
午酉丑,(右弼)9: Investment and Reputation


Practitioners and Enthusiasts are often confused with this Xuan Kong Poem or Verse that points to a triangulation set up. This triangulation set up is somewhat similar to that of a spell circle in wicca.

From an application aspect, practitioner are often confused with whether to apply water or Qi as well as the “how to” in pinpointing the exact spot to apply the activation.

The key to the power of these energy resides in the 8 stars in Big Xuan Kong (大玄空挨星). And the application sits on the 64 sectors of Xuan Kong Da Gua (玄空大卦) ring.

First, the user needs to have some knowledge of XKDG and be able to determine the current period (upper cycle or lower cycle) we are at and apply the chart. In this XKDG triangulation application, one of the 3 spots needs to be a door or window, this is regarded as Qi Mouth.

In this period 8 (year 2023) and next year onward period 9 (year 2044 till 2063), we would be using lower cycle chart.

In the XKDG ring, the lower cycle chart has 2 sets of number. An upper number that relate to HeTu and a lower number that symbolise the luck period.

Taking Jia Gui Shen – 甲癸申 to trigger 贪狼 – “Greedy Wolf” for example, the upper number need to form a HeTu (16, 27, 38, 49), combo of 5-10-15. After this upper number set is determined, look at the lower number. When in the lower cycle the number 6, 7, 8, 9 is to apply fire or Qi while the number 1, 2, 3, 4 can apply water activation.

Of course, when one activates Greedy Wolf energy, one must be ready to take on new challenges in business or career when being thrown at. Each of these stars and its energy signature also have their flip sides and shortcomings.

This is (in a nutshell) the XKDG spell circle triangulation to activate the relevant energy to support the human activitiy and goals. Instead of doing the spell circle in wicca, the XKDG triangulation activates and draws in a larger amount of energy for manifestation in an enduring positive light perspective.

天醫貴人 (Heavenly Doctor)

Using Early and Later Heaven Ring in Xuan Kong Liu Fa

Explorers of Xuan Kong won’t be alien to one of the literatures called Xuan Kong Liu Fa (XKLF) or also known as the 6 Methods of Xuan Kong.

The 6 Methods of Xuan Kong comprises of 1. 玄空-Xuan Kong, 2. 雌雄-Ci Xiong, 3. 金龙-Golden Dragon, 4. 挨星-Ai Xing, 5. 城门-Chen Men and 6. 太岁-Tai Sui. Of which, the most useful and yet misunderstood is 挨星-Ai Xing.

While some authors downplay the early heaven ring, some Practitioners completely omitted it in assessment.

This 2 rings – Early and Later Heaven basically rooted back to an I-Ching fundamental. 先天为体,后天为用 – Early Heaven as the Body and Later Heaven as Use. Now, replace the word ‘Body’ with the word ‘Link’ and the word ‘Use’ to the word ‘Application’ and it will all be clear in our present context. Below is an abridged explanation for those with affinity to see this passage.

先天为体 (Early Heaven as Link)→Look at the Early Heaven ring (it comprises of a ring of numbers) on the compass to identify if the 2 Gua (卦) or sectors can connect. The key to connect is via combo (5, 10, 15), Same Numerals or HeTu (16, 27, 38, 49). For example, E2 and NE2 (卯 and 艮) is able to pair with 4,9 HeTu combo.


后天为用 (Later Heaven as Application)→ For those Gua (卦) or sectors that can connect, refer to the Later Heaven ring to see if it the Gua (卦) number is 1,2,3,4 or 6,7,8,9. And we apply water or fire activation depending on the period we are in. For example, E2 and NE2 (卯 and 艮) has the number 6 and 7, which is a lower cycle number; hence to apply air flow, Qi, movement, using of that sector or fire in form of candles. As per what the western world call: Direct and Indirect Spirit.


The important key or secret lies in the application of 挨星-Ai Xing resides in above image/ chart, where it narrates the 3 groups of gua (卦). Heaven and Earth Parent Gua (天地父母卦), Thunder and Wind Eastern Gua (雷风江东卦) and Mountain and Lakes Western Gua (山泽江西卦). The key is to use only those Gua that are of the same group. This alignment allows each gua to communicate with each other as they are of the same family. For example, the door is in the Xu-Dog sector. As such, Ren-Water sector can be activated to bring in Nobleman, Reputation and Business Prosperity.

With this the most useful and yet often misunderstood 挨星-Ai Xing application has been comprehensively explained and demystified. When applied with 玄空-Xuan Kong and 雌雄-Ci Xiong, the application of 挨星-Ai Xing will not just be confined to the house layout but be more dynamic.
