The Creator has one true name which is represented by the letters YHVH in English. The Hebrew letters are "yud, hei, vav, hei". These four letters are referred to as the tetragrammaton and are a contraction of the Hebrew words for, "was, is, and will be". His true name was only said in the Temple and with the Temple's destruction we lost the correct pronunciation.
