unseen crown of the head ［無見頂相］ ( mukenchō-sō): The top of a Buddha’s head, which no one can see. One of a Buddha’s eighty characteristics. It is said that the crown of a Buddha’s head cannot be seen by humans or heavenly beings. This feature is generally identified with a protuberant knot of flesh on the crown of a Buddha’s head, one of a Buddha’s thirty-two features. For this reason, the unseen crown of the head is also counted as one of the thirty-two features.
