Re-presenting a known meaning to the mind is the second benefit. Repeated attention can deepen intellectual understanding and strengthen the dispositions connected to it. Grasping an idea once does not always complete the work of education.
A person who already knows the meaning of a cherished verse of poetry may experience renewed appreciation when hearing it again. Likewise, a recognized religious truth can become more vivid when expressed in a new setting. Recurrence brings the meaning actively before the mind rather than merely repeating words.
The distinction: the first benefit initiates understanding; the second deepens, renews, and reinforces what was already understood.
