大乘起信論略述 2.27

2.27

[Treatise:] Even if there are external conditions, [...] joyfully seeking nirvāṇa. [Commentary:] This reveals the lack of cause. This means that when there is the defilement of avidyā's thick perfuming, even though original awakening constantly initiates internal perfuming, because of avidyā's perfuming the [internal] perfuming lacks force. Even if one encounters the force of the external conditions of good friends, they still cannot cause one to attain the Way.
