Enchin presents his own interpretation regarding this passage using six identities and reflects on the near and far in vyākaraṇa as well as the ripe and unripe in relation to the capacities of beings. He quotes many commentaries to support his views on these subjects, such as Zhiyi’s Fahua-wenju 法華文句 and Zhanran’s Fahua-wenju-ji 法華文句記.
Overall, quotations from commentaries by the likes of Zhiyi and Zhanran occupy a considerable portion of the latter half of the seventh volume. In addition, the author generally follows quotations from Ji’s 基 Fahua-xuanzan 法華玄賛 with those from Zhiyi’s Fahua-wubaiwenlun 法華五百問論 to refute views found in the former. Furthermore, in the second half of the latter half of the seventh volume he temporarily ends his annotations by stating, “The interpretation of our sect is what has been discussed in detail above,” and then follows the remark, “Now I will present other interpretations to aid in the understanding of the marvelous meaning,” quoting teachings from the Linzutan-jing 六祖壇経 over the course of twenty-four lines.
