Peter Damian]: "Your hearing is as mortal as your sight;
Just as Dante's mortal sight could not endure the brilliance of Beatrice's smile here in the Seventh Heaven, his equally mortal hearing could not endure any of the blessed souls' singing, were they to hymn. It seems that the blessed souls make allowances for Dante, reining in their various superhuman qualities to ensure Dante's well-being.

But time between one and other when
The reference to "heaven grow[ing] more radiant" and Beatrice's later allusion to "the triumphant Christ" implies that Jesus is like a sun to this heaven. Indeed, his followers are described as "fruits / ingathered," which probably come from the work of the Holy Spirit. And the congregation of so many shining souls is compared to "a thousand lamps," whose collective light is so bright that Dante goes temporarily blind.

Even as he who squints and strains to see
St. John's appearance in his clothing of light is so brilliant that Dante "becomes sightless." The comparison of St. John to a "sun somewhat eclipsed" may refer to his wisdom, extending far beyond that of the souls located in the sun.
