। ॥ १०८ ॥
In plain words
The sun is hidden by clouds that its own rays raised up. But the day-ness of the day is not touched by them — not by those thick, piled-up banks, which are only alterations.
Close to the Sanskrit
Just as the sun is covered by clouds arisen from the day-maker's own rays — the day-ness of the day is surely not [taken away] by those altered, dense masses.
