Sak yant designs are normally tattooed by wicha (magic) practitioners and Buddhist monks, traditionally with a long bamboo stick sharpened to a point (called a mai sak) or alternatively with a long metal spike (called a khem sak).
The script used for yantra designs is a mixture of ancient Khmer script and the original Buddhist Pali script. Records have shown that yantra tattooing dates back to Angkor times.[citation needed] Different masters have added to these designs over the years through visions received in their meditations. Some yantra designs have been adapted from pre-Buddhist Shamanism and the belief in animal spirits that was found in the Southeast Asian sub-continent and incorporated into the Thai tradition and cultures.
