經曰「十方世尊」至「忍終不悔」者，述云：此後、請十方佛證行不悔也。對佛結誓，身止諸苦，勤忍不悔故。

On the passage where the sūtra states, "The World-Honoured Ones of the ten directions..." up to "endure to the end without regret": The commentary states: This is, following that, requesting the buddhas of the ten directions to bear witness that his practice will not be regretted. Making vows before the buddhas, he will endure all physical suffering, striving and enduring without regret.
