其以方便現身有疾　此下第二現疾益物文四。一明方便現疾。二諸人參問。三因為說法。四聞法得益。此初也。肇曰。雖復變現殊方妙迹不一。然此經之起本于現疾故作者別序其事也。

"Through upāya he manifested illness in his body." Here begins the second [section], "Manifesting Illness to Benefit Beings," which has four parts: first, explaining the manifestation of illness through upāya; second, the people coming to inquire [after his health]; third, expounding the Dharma for them accordingly; and fourth, hearing the Dharma and gaining benefit. This is the first part. Sengzhao states: "Although he manifests varied transformations and extraordinary traces that are not just one, nevertheless the arising of this sūtra is fundamentally rooted in the manifestation of illness; hence the author specifically introduces this matter."
