Chih-i displays the gist in terms of the cause and effect of Buddhahood in the Traces and in the Origin that are stated in the Lotus Sūtra. He says that the gist of the Lotus Sūtra refers to the combination of the cause and effect of Buddhahood in the Origin (stated in the latter half of the Lotus Sūtra), and the cause and effect of Buddhahood in the Traces (stated in the first half of the Lotus Sūtra).
