法華義疏 8.228

8.228

如《大品》數處明之，一者、約有方便無方便明其難易，無方便故為難、有方便故為易，難易出兩緣耳，菩提實無難易。又世諦門明菩提難得，第一義門菩提易得。又為輕賤佛道眾生故言菩提難得，為怖畏生死長遠眾生故言菩提易得也。

As explained in several places in the Pañcaviṃśatisāhasrikā Prajñāpāramitā Sūtra: first, difficulty and ease are explained in terms of having upāya or lacking upāya. Because one lacks upāya, it is difficult; because one has upāya, it is easy. Difficulty and ease simply arise from these two conditions; bodhi in reality has neither difficulty nor ease. Furthermore, the approach of conventional truth explains that bodhi is difficult to attain, whereas the approach of ultimate truth explains that bodhi is easy to attain. Moreover, for the sake of sentient beings who hold the Buddha-Way in slight regard, it is said that bodhi is difficult to attain; for the sake of sentient beings who dread the long expanse of saṃsāra, it is said that bodhi is easy to attain.
