Prick the skin, hold the power. The ink is a device, not a picture.

A tattoo that is a working object: geometry and syllables in an old script, applied by a master, carrying protection, fortune, charisma or fear — and conditional on rules the bearer keeps afterwards.
The long version
Where it comes from. The practice is dated to the Khmer Empire around the ninth century, resting on Mainland Southeast Asian animist tattooing that goes back far further, with the geometry taken from Indian yantras. It is Cambodian, Lao, Thai and Burmese, and it does not belong to one of them.
What the script tells you. There is no single alphabet for this. In Cambodia, Khmer script. In central Thailand, Khom — the Khmer-derived script used there for Pali and for anything sacred. In the north the yant is written in northern Thai, Shan or Tai Lu script, and in Laos in Lao Tham. A yant done in Chiang Mai and a yant done in Nakhon Pathom are not written in the same letters. The alphabet on a person's back is a map of where their master's lineage is from, and it is the first thing to read.
Three kinds of effect, in the article's own division: what benefits the bearer — eloquence, charm; what protects — warding off harm, which is why it is carried by soldiers, police, taxi drivers and anyone whose work is dangerous; and what acts on other people, including invoking fear.
And it is conditional. The power holds only while the bearer keeps the rules and the taboos that came with it, which can include abstaining from a particular food. It also fades with time, which is why masters re-empower their disciples' tattoos once a year at Wai Khru.
In this sport. A fighter's whole ritual kit is the same practice in different materials: the mongkhon blessed by a monk, the prajiat tied round the arm, the takrut rolled in metal, and the yant under the shirt. They carry the same syllables, from the same masters, for the same reasons. The difference is only whether the surface can be taken off.
How
The word. Sak (สัก) is to prick, a native Khmer word from a Mon-Khmer root cɔkʔ, to prick — not a Sanskrit loan. Yant is yantra (यन्त्र), from Sanskrit yam, to hold or sustain, plus tra*, an instrument. A yantra is an instrument for holding something in place. The name says exactly what the thing is meant to do.
The needle. A khem sak about eighteen inches long and four millimetres wide, the tip split so each strike puts down two dots. A typical design takes about three thousand strikes. The needle is dipped every thirty seconds into a mix of oil, Chinese charcoal ink, and — the account says possibly — snake venom.
The finish. When the drawing is done the master blesses it and blows a kata onto it, and that is the step that makes it work. The ink without the breath is a drawing.
