阿彌陀經通贊疏 1.77

1.77

"Mahākapphiṇa" is translated as "Lodging in the Same Room." The Buddha lodged in the same room with him, transformed into an old monk, and preached the Dharma for him, through which he attained the Path; hence he is called "Lodging in the Same Room." Through the Buddha's conversion and guidance, his arrogant mind was eliminated. For this venerable one, the World-Honoured One concealed his holy marks and manifested a monastic appearance, walking alongside him holding a golden staff and lodging together in a thatched hall; knowing his faculties were ripe, [the Buddha] resumed his original form, and seeing the marks and signs [Kapphiṇa] aroused the resolve, and hearing the subtle words he ceased his arrogance; hence it is called "eliminating arrogance."
