Chapter 13: Khuen Thao Thang Si: The Axis-Mundi Mast, the Six Directional Trays, and Lanna's Celestial Guardian Perimeter
Explore Lanna's Khuen Thao Thang Si: the single axis-mundi mast, the six directional Sa-tuang trays, and the Pu Achan's rites sealing festive perimeters.
The Primordial Injunction: The Prerequisite to Auspicious Gatherings
In the traditional liturgical calendar of ancient Lanna, no auspicious celebration could commence without formal spiritual authorization. Whether staging a monumental community festival like a Poy Luang (the grand consecration of a vihara, stupa, monastic wall, or civic school), a Poy Noy (an ordination ceremony for monks and novices), or household milestones like housewarmings and weddings, customary law imposed an immutable prerequisite: The rite of "Khuen Thao Thang Si" (The Raising of the Four Heavenly Kings) had to be fully consummated before any subsequent celebration could begin.
Sanguan Chotisukharat explains that this ceremony served as a formal diplomatic treaty with the Four Great Heavenly Kings (Catu-Lokapāla) of the Catumaharajika heaven: Dhatarattha (Guardian of the East), Virulhaka (Guardian of the South), Virupakkha (Guardian of the West), and Vessavana (Kuvera, Guardian of the North). By tendering consecrated food tributes, the community invoked their martial omnipotence to establish an unbreachable psychic barrier, expelling demons, curses, and malicious entities from the ceremonial grounds.
Architecture of the Axis Mundi: The Single Mast and the Six Cosmic Trays
At the physical perimeter of the festival grounds, an ephemeral sacred installation was constructed, serving as an architectural model of the Buddhist cosmos:
- The installation was anchored in the auspicious corner of the site, oriented toward the East or the North-East (the traditional quadrant of spiritual awakening).
- A fresh tree trunk or sturdy banana trunk was planted upright in the earth to form a single pillar (Sao Diao), elevated slightly above waist height.
- Affixed horizontally to the top of the pillar was a four-armed wooden crossbar (Rup Kakabat), pointing to the four cardinal directions to serve as platforms for sacrificial trays.
The mystical genius of the installation lay in the configuration of six square banana-bark trays (Sa-tuang) balanced upon this single axis-mundi pole:
- The Four Cardinal Trays: Four Sa-tuang trays rested upon the four ends of the crossbars, dedicated individually to the Four Heavenly Kings guarding the cardinal quadrants.
- The Zenith Tray (Indra's Crown): Rising roughly one span (Kheup) directly from the center of the crossbar stood a raised wooden peg holding the fifth tray, dedicated to Phra In (Sakka / Indra), the supreme sovereign of Tāvatiṃsa Heaven.
- The Nadir Tray (The Earth Mother): Resting directly on the raw sod at the base of the mast sat the sixth tray, dedicated to Mae Phra Thorani (The Earth Goddess).
Each of the six trays was lined with fresh banana leaves and packed with miniature offerings: betel nuts, fermented tea (Miang), local cigars, bananas, sugarcane, sour and sweet curries, cooked rice, confections, popped rice, flowers, tapers, and tiny colorful paper pennants (Chor) and banners (Tung) pinned along the margins.
The Litany of the Pu Achan: Sealing the Perimeter
The homeowner or festival host could not execute this rite; it required the esoteric mediation of the "Pu Achan" (the elder lay master of the village temple):
- The host presented the formal master's tray (Khan Tang), laden with popped rice, fresh flowers, incense, tapers, traditional skeins of betel nuts (Mak Mai), teacher's coins, and a mandatory bottle of liquor.
- Seated before the altar, the Pu Achan ignited the candles, paid homage to his pedagogical lineage, and unrolled his ancient accordion-folded mulberry paper manuscript (Pap Sa). He declaimed the "Ongkan Khuen Thao Thang Si" (The Cosmic Proclamation of the Four Regents) in a loud, commanding, resonant baritone.
The liturgical proclamation formally summoned the regents of the six cosmic directions, naming the hosts, delineating the physical boundaries of the celebration, and entreating the celestial kings to "stake down the perimeter" with their divine armor. Once the Pu Achan uttered the concluding seals of the text, the grounds were recognized as an inviolable sanctuary, cleared of spiritual pollution and ready to stage the grandest festivals under the absolute guardianship of the gods.
