The mantra might be in Sanskrit or any other language, either one's native tongue or the language of one's chosen religion. Some of the more brief meditation mantras are simply sound vibrations that are not from any particular language, though being root sounds of languages. These are called seed or bija mantras. Often the mantra is prescribed by one's teacher or lineage, or is practiced in accordance with one's religious affiliation. Or it might be a universal mantra such as the Soham mantra.
