Siman 231

(2.) I heard from one person who heard from Rabbainu o.b.m. who told him about the immensity of his holiness in childhood — that when he was a small child he wanted to be G-d-fearing and he desired to receive the Sabbath with great holiness as was fitting. And he went to the bathhouse and immersed immediately with alacrity just after midday. And he came out of the immersion and came home and dressed in Sabbath garments and entered the house of study and walked about here and there, wanting to draw upon himself the sanctity of the Sabbath and the additional Sabbath soul. And he desired greatly to see something but saw nothing at all. And he was very longing to see. And in the midst of this, people began to enter the house of study and some important man came and stood at his lectern and began to recite the Song of Songs. And he o.b.m. went and placed his head underneath the lectern. And since he was still a small child no one took issue with him. And he lay there and began to weep — and wept very greatly with abundant tears for several hours until the evening — until his eyes swelled up. And afterwards he opened his eyes and it seemed to him as if he saw some light because the candles had already been lit, and his eyes were so sealed from weeping. And then his mind was somewhat at ease. And it seems he said he was then about six years old.
