Luang Pho Sud of Wat Kalong: monastic education and the Yant Takro tradition
Luang Pho Sud Siritharo (หลวงพ่อสุด สิริธโร), formally titled Phra Khru Samut Thammasunthon, was the long-serving abbot of Wat Kalong in Samut Sakhon. Chinese-language amulet markets use several transliterations, including 龍婆肅 and 龍婆素. These variants refer to the same monk; retaining the Thai name is the clearest way to avoid mistaking spelling differences for separate people.
He was born on 7 May B.E. 2445 (1902) in the Phanom Phrai area of Roi Et. His family name was Sattang; his parents were Mak and Onsi. He became a novice at Wat Fa Yat on 16 April B.E. 2461 and received full ordination at Wat Klang Phanom Phrai on 20 June B.E. 2465, taking the monastic name Siritharo.
His formation was not limited to ritual knowledge. He passed the elementary Nak Tham examination in B.E. 2466, the intermediate level in B.E. 2471, and, after further study at Wat Tuek Maha Chayaram in Samut Sakhon, the advanced level in B.E. 2481. Nak Tham is Thailand's monastic Dhamma curriculum, not a modern university degree.
Biographical records place him with Phra Khru Wirot Rattanobon, known as Luang Pu Rot, at Wat Thung Si Mueang in Ubon, and later with Luang Pu Toh at Wat Pradu Chimphli in Bangkok. They also name teachers in central Thailand including Luang Pho Rung of Wat Tha Krabue, On of Wat Bang Khut, Sai of Wat Nong Song Hong, Chai of Wat Sadet, Khong of Wat Bang Kaphom, Tae of Wat Sam Ngam and Chaem of Wat Takong. Later accounts associate his studies with takrut, yantra, traditional tattooing and herbal knowledge. Such lineage accounts provide context; they do not authenticate an individual object.
In B.E. 2475 he began administering Wat Kalong and subsequently became its abbot, serving for roughly fifty-one years until his death. He received local ecclesiastical responsibilities from B.E. 2479 onward. The title Phra Khru Samut Thammasunthon was conferred at third class in B.E. 2490, promoted to second class in B.E. 2511 and first class in B.E. 2517.
Temple accounts describe a disciplined, modest monk who expected monks and novices to study Dhamma. His administration supported a temple school, roads and buildings. The ordination hall was built between B.E. 2500 and 2506, while a road connecting the community to Rama II Road improved access. Education and local infrastructure are therefore central to his legacy, not footnotes to an amulet story.
His signature yantra was Yant Takro, the woven-rattan-ball yantra, also called Yant Sai Hanuman in some accounts. A takraw ball withstands repeated kicks and impact while retaining its interlocked structure. Devotional tradition reads this as resilience and protection. That meaning belongs to religion and folklore; it is not a scientific guarantee of physical safety.
The same records place ethical conditions before the design itself. At the time, candidates were expected to come from the Ban Kalong community, to have spent at least one rains retreat in robes, and to be judged likely to behave well after returning to lay life. Three prohibitions are recorded: not sleeping directly on a wooden-plank floor, not insulting another person's parents, and not committing sexual misconduct. The tradition therefore joined restraint and responsibility to its protective symbolism. This article records the cultural and ethical framework without teaching the tattoo procedure or formula.
Takrut associated with him include a single waist cylinder of about four inches, commonly copper or brass and generally dated to B.E. 2515–2520, and a waist cord made from many small pieces in silver, brass and copper, often called the 108-takrut or three-kings set. Material, measurements, handwriting, provenance and reliable comparison pieces must still be examined item by item. A Yant Takro motif alone is not proof of authenticity.
An early portrait medal dated B.E. 2506 was connected with the boundary dedication of the ordination hall. It later acquired the collector nickname “lightning medal” and protective stories, which should be treated as collecting history and oral tradition rather than independently verified events.
The B.E. 2517 medal marking his sixth cycle and seventy-second birthday became one of his best-known series, often called the leaping-tiger medal. The tiger refers to his Tiger-year birth, while Yant Takro appears on the reverse. A separate B.E. 2517 promotion medal with a ceremonial-fan design is also documented. Issues sharing a year should not be collapsed into one type; design, metal and purpose must remain distinct.
These objects also belong to the political and social climate of 1970s Thailand, when conflict connected with anti-communist campaigns heightened concern for personal safety. Sacred objects could serve as morale for soldiers and police. Claims of invulnerability or escape from danger remain devotional claims, not safety advice, and no one should test an amulet through hazardous behaviour.
Other objects connected with him include early powder Somdet forms, a B.E. 2507 medal, the large sanghati medal of B.E. 2515, a crouching-tiger medal and 108-takrut set of B.E. 2519, tiger-return and small-tiger issues of B.E. 2521, homeland-lotus medals of B.E. 2522, and later issues through approximately B.E. 2525. Each requires separate study by date, mould, material and documented source.
Luang Pho Sud died peacefully at Wat Kalong at 1:15 p.m. on 14 August B.E. 2526 (1983), aged eighty-one years, three months and eight days. Stories concerning his body and cremation remain part of temple and community memory; they are belief narratives, not verified medical or historical facts.
To remember him only through claims of miraculous power would flatten a much larger life. His education, discipline, administration and community work explain the setting from which Yant Takro emerged. For collectors, a responsible approach separates history, lineage and claims while examining provenance, type, metal and comparable objects. For a wider audience, the most durable lesson of the woven ball may be neither invulnerability nor profit, but the ability to preserve structure, discipline and ethical conduct under repeated pressure.
