5.246

舉疑處。經意云：汝意之中，頗謂我於然燈佛所得菩提不？若得菩提，何成菩薩？是彼疑處，故舉問之。

Presenting the point of doubt: the sūtra's intent is: "In your thought, do you hold that I attained bodhi in the presence of Dīpaṃkara Buddha or not? If I attained bodhi, how could I have become a bodhisattva?" This is the point of that doubt, so it is raised as a question.
