大乘起信論略述 2.29

2.29

論。用熏習者至外緣之力　述曰。下明用熏。於中有二。初指事總標。後約緣別顯。此初也。謂佛等菩薩所起作用大悲弘誓應現所起作多方。但預見聞無不蒙益故。是眾生外緣之力。

[Treatise:] Perfuming by function […] the power of external conditions.
[Exposition:] Below, perfuming by function is explained. In this there are two parts: first, a general designation indicating the matter; next, a specific elucidation with reference to conditions. This is the first. It means that the functions initiated by the buddhas and bodhisattvas, their adaptations manifesting from great compassion and broad vows, are initiated through many means; and whenever anyone happens to see or hear them, none fail to receive benefit. Therefore, they are the power of external conditions for sentient beings.
