無量壽經連義述文贊 3.64

3.64

經曰「等觀三界」至「煩惱之患」者，述云：此第三、行修具足。有二：此初、修行也。觀三界空無者，即捨生死行。欲等三界，無有一界而不空者，故云等觀。志求佛法者，即欣菩提行。具辯才者，即利他之德，所謂四辯等。滅煩惱患者，化他之益。

The sūtra says: "Equally contemplating the three realms... the suffering of afflictions." The commentary states: This is the third [section], the full perfection of cultivation and practice. It has two parts: this first part is their cultivation and practice. Contemplating the three realms as empty and non-existent is the practice of relinquishing saṃsāra. Regarding the three realms—the desire realm and so forth—there is no realm that is not empty; hence it says "equally contemplating." Aspiring to seek the Buddhadharma is the practice of delighting in bodhi. Possessing eloquence is the virtue of benefiting others, namely the four eloquence and the like. Extinguishing the suffering of afflictions is the benefit of transforming others.
