金光明最勝王經疏 3.191

3.191

贊曰：結不異也。由前五如如故，諸佛體不異。意顯如同，修之皆得，故云諸佛體無有異。

Commentary: This concludes their non-difference. Due to the preceding five tathatās, the substances of the buddhas are not different. The intention is to reveal that tathatā is identical: all who cultivate it attain it; hence it says, "the substances of the buddhas have no difference."
