This directly illustrates this section of text that resolves doubts. It means that when the cataract is cured, one sees the flowers cease in the sky; although the flowers cease, the sky is always present. However, when the flowers arise they do not arise, and when they cease they do not cease; it is because of the cataract and its cure that one sees arising and sees ceasing.
