高僧傳 10.35

10.35

There was also Du Seng'ai, who lived beneath Nangang, who had formerly served Beidu. His son became critically ill, and he thought with regret of not having obtained Beidu's practiced divine incantations. The next morning he suddenly saw Beidu arrive, speaking just as usual. He immediately recited an incantation for him, and the sick boy was cured.
