佛說盂蘭盆經疏 2.16

2.16

Question: Examining this sūtra text, it is shallow and rustic, specifically warning the poor and lowly—why is this? Answer: The gentleman is naturally filial; therefore, it specifically warns the petty person. Moreover, the gentleman also experiences the poverty of a single bamboo dish and gourd ladle; what prevents him from engaging in tasks such as pounding and milling? Furthermore, it is only by specifically recounting words of hardship and toil that the labor of nurturing and rearing is truly made manifest.
