3.49

照心識具德者，對給孤獨也。上迷本覺之父曰孤，下隱妙用之子曰獨。今照性本具塵沙功德無所乏少，即給孤獨也。求法等，對比丘乞士義也。外則乞食養命，內則求法資神。

"Illuminating the mind-consciousness as possessing virtues" corresponds to Anāthapiṇḍada. Above, being deluded about the father of original enlightenment is called "orphaned" (gu); below, concealing the son of wondrous functioning is called "solitary" (du). Now, illuminating that nature originally possesses merits numerous as grains of sand without any lack is precisely Anāthapiṇḍada. Seeking the Dharma and so forth corresponds to the meaning of a bhikṣu as a mendicant. Externally, one begs for food to sustain the body; internally, one seeks the Dharma to nourish the spirit.
