大乘起信論略述 2.37

2.37

論。所謂眾生至見諸佛故　述曰。此遣外疑釋平等義。謂外疑云。若謂能現平等緣用。何故眾生見差別耶。故此釋云。謂平等緣應平等機。平等機者。謂三賢上諸眾生等依三昧力悉見諸佛。身量平等無有彼此分齊之相。故云平等見諸佛也。

[Treatise:] Sentient beings […] see all buddhas.
[Exposition:] This dispels an external doubt and explains the meaning of "equality." The external doubt says: If it is said that they can manifest equal conditions and functions, why do sentient beings see distinctions? Therefore, this explains: equal conditions respond to equal capacities. "Equal capacities" refers to sentient beings above the three grades of worthies and so forth, who, relying on the power of samādhi, completely see all buddhas. The dimensions of their bodies are equal, without characteristics of delimitation between self and other; hence it says "equally seeing all buddhas."
