Khatha inscriptions
When a Khatha is inscribed on paper, cloth, metal, skin, or any other surface for that matter, it is traditionally done using the Ancient Khmer Alphabet (known as "Phasa Khom", or "Khom" in Thai language). The Khmer (Khom) alphabet is only permitted to be used for sacred or magical texts, and never for common speech or everyday matters. This alphabet is considered by some Thai people to be extremely sacred and to possess Magical power within the letters. This is the lettering seen used in Sak Yant Tattoos.
