The Engishiki can be divided into two parts in accordance with the two major divisions of the government: the Jingi-kan concerned with kami (deities) affairs or Shinto religion for the well-being and prosperity of the national community, and the Dajō-kan dealing with all the ‘secular’ business of the government. All matters handled by the Jingi-kan are found in the first ten books of the Engishiki.
