《史记·八书·天官书》
普通经星的变化很少见；而对日、月、五星等三光变化进行占卜却是常常使用的；占日月晕的次数在两者之间。
夫常星之变希见，而三光之占亟用。
Changes in ordinary perennial stars are rarely seen; however, divination based on the changes of the three luminaries, namely the sun, moon, and the Five Planets, is frequently used; divination based on solar and lunar halos falls somewhere in between.
