Zohar 3:61a

Jewish Mysticism
It has been taught- the images of all those who are occupied with [the study of Torah] during the night are engraved above before the Holy One, blessed be He, and the Holy One, blessed be He, takes delight in them all day and looks at them. That voice [of one engaged in Torah-study] rises and breaks through all the firmaments until it ascends before the Holy One, blessed be He… Now the Holy One, blessed be He, engraves the image of R. Simeon above, and his voice ascends and is crowned by the holy crown until the Holy One, blessed be He, is crowned by it in all the worlds and is glorified by it.
