觀無量壽佛經疏 4.3

4.3

今言三福者。第一福，即是世俗善根。曾來未聞佛法，但自行孝養仁義禮智信，故名世俗善也。第二福者，此名戒善。就此戒中即有人、天、聲聞、菩薩等戒，其中或有具受、不具受，或有具持、不具持，但能迴向盡得往生。第三福者，名為行善。此是發大乘心凡夫自能行行兼勸有緣，捨惡持心迴生淨土。

Now, concerning the three meritorious deeds: The first meritorious deed is the worldly roots of goodness. Having never heard the Buddha-Dharma before, one merely practices on one's own filial care, benevolence, righteousness, propriety, wisdom, and trustworthiness; hence it is called worldly goodness. The second meritorious deed is called the goodness of precepts. Within these precepts are human, deva, śrāvaka, and bodhisattva precepts, among which some receive them fully or not fully, and some uphold them fully or not fully; but if they can dedicate [the merit], all will attain rebirth. The third meritorious deed is called the goodness of practice. This refers to ordinary beings who give rise to the Mahāyāna mind, are personally able to perform practices while also exhorting those with karmic affinity, abandoning evil and guarding the mind, dedicating it to be reborn in the Pure Land.
