For persons who have a knowledge about kanbun, it may not be so difficult to read it as 'tsuneni gessho wo motte senji ni kuwae, Nisshininyo wo mite motte shika wo tatsu.' (Gessho and the time should always be used for divination and Shika should be derived by seeing Nisshinonmyo).
これを　「常に月将を以て占時に加え、日辰陰陽を視て以て四課を立つ。」　と読み下すことは、漢文の知識があればさほど困難ではない。
