分別功德論 2.19

2.19

當修行一法者，謂念佛也。念佛何等事？佛身金剛無有諸漏，若行時足離地四寸，千輻相文跡現於地。足下諸蟲蟻七日安隱，若其命終者皆得生天上。昔有一惡比丘，本是外道，欲假服誹謗。逐如來行，多殺飛蟲著佛跡處，言蹈蟲殺也。然蟲雖死，遇佛跡處尋還得活。若入城邑足蹈門閾，天地大動，百種音樂不鼓自鳴，諸聾盲瘖瘂癃殘百疾自然除愈。三十二相八十種好，其有覩者隨行得度。功德所濟不可稱計，慧明所照豈可訾哉。佛者諸法之主，總會萬行以載運為先。所謂念佛，其義如此。

Regarding “One should cultivate one dharma”: this refers to mindfulness of the Buddha (buddhānusmṛti). What manner of matter is mindfulness of the Buddha? The Buddha's body is adamantine and free from all defilements (āsrava). When he walks, his feet are four inches above the ground, and marks with the pattern of a thousand-spoked wheel appear upon the earth. The insects and ants beneath his feet remain secure for seven days, and if their lives come to an end, they are all reborn in heaven. Formerly, there was an evil monk who was originally a non-Buddhist and wished to don the robes deceitfully in order to slander [the Buddha]. Following behind the Tathāgata as he walked, he killed many flying insects and placed them in the Buddha’s footprints, saying that [the Buddha] trod on insects and killed them. However, though the insects were dead, when they met the Buddha’s footprints, they immediately returned to life. When he enters a town or city and his foot steps upon the threshold, heaven and earth shake mightily, a hundred kinds of music play without being struck, and the deaf, blind, mute, crippled, and afflicted with a hundred illnesses are naturally cured. He possesses the thirty-two marks and eighty secondary signs, and whoever beholds them attains deliverance in accordance with their practice. The beings saved by his merits cannot be reckoned, and how could the illumination of his radiant wisdom ever be deprecated? The Buddha is the master of all phenomena (dharma), uniting the myriad practices with carrying [beings] across as foremost. Such is the meaning of what is called mindfulness of the Buddha.
