無量壽經連義述文贊 3.39

3.39

經曰「若人無善本乃獲聞此經」者，述云：第二、釋迦自歎。有三：初、歎經難信；次、佛智難思；後、勸使發心。初又有二：此初、以有善聞。歎經微妙也。

On the sūtra's words, "If a person lacks roots of good, they will not obtain the hearing of this sūtra," the Commentary states: Second is Śākyamuni's praise of himself. It has three parts: first, praising the sūtra as difficult to believe; next, the Buddha's wisdom as difficult to conceive; last, exhorting beings to generate the mind [for bodhi]. The first part also has two: this first praises the subtlety and wondrousness of the sūtra through having goodness to hear it.
