說無垢稱經疏 6.60

6.60

贊曰：此陳遣信。所以稱揚我及此土，令彼菩薩善根增故。即前所說當欣大慧，此答前問從何處來。

Commentary: This explains dispatching the messenger. The reason is to praise me and this land so that those bodhisattvas' roots of goodness may increase. This corresponds to what was said earlier about 'they will delight in the great wisdom', answering the earlier question of where he came from.
