Agyō Misshaku Kongō (密迹金剛), also called Agyō (阿形) is a symbol of overt violence: His mouth is depicted as being in the shape necessary to form the "ah" sound, leading to his alternate name, "Agyō"
Kongōrikishi (金剛力士) or Niō (仁王) are a pair of muscular guardians of the Buddha, standing at the entrance of many Buddhist temples in the form of frightening wrestler-like statues. They are manifestations of the Bodhisattva . 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 (ɦ)) which is pronounced "ɦuṃ" (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.) they signify "everything" or "all creation". According to Japanese tradition, they travelled with the historical Buddha to protect him. Niō guardians justified the use of physical force to protect cherished values and beliefs against evil.
