Commentary
Book Nine Miscellaneous Poems I 592

The waters of the Mitarashi River, long heard of, are so clear, the poet says, that just as its bed shows through, today he shall see to the depths of the other's heart. Through the purity of the shrine's purification stream, he hopes at last to confirm the sincerity of the other's heart today.
