Manifestations
Kongōrikishi are usually a pair of figures that stand under a separate temple entrance gate usually called Niōmon (仁王門) in Japan, Heng Ha Er Jiang (哼哈二将) in China and Geumgangmun (金剛門) in Korea. The right statue is called Misshaku Kongō (密迹金剛) and has his mouth open, representing the vocalization of the first grapheme of Sanskrit Devanāgarī (अ) which is pronounced "a". The left statue is called Naraen Kongō (那羅延金剛) and has his mouth closed, representing the vocalization of the last grapheme of Devanāgarī (ह ) which is pronounced "ɦūṃ" (हूँ). These two characters together symbolize the birth and death of all things. (Men are supposedly born speaking the "a" sound with mouths open and die speaking an "ɦūṃ" and mouths closed.) Similar to Alpha and Omega in Christianity, they signify "everything" or "all creation". The contraction of both is Aum (ॐ), which is Sanskrit for The Absolute.
