大乘起信論義記 3.118

3.118

問：此中妄心既並熏習真如起返流行，意熏既屬梨耶，如何能各自發心修行？答：前凡夫二乘不覺梨耶，但依分別事識資持力故而發心修行，以不達本故，向大菩提疏而且遠，故云漸也。此菩薩既了梨耶本識，即依此識資持力，方得發心修行。以了本故，向大菩提親而且近，故云速也。此約所依相資辨熏，非各自發心等，此如下文證發心中說。

Question: Here, since the deluded mind equally perfumes tathatā to initiate practice that turns against the stream, and since the perfuming of the manas belongs to the ālaya[vijñāna], how can each independently give rise to the aspiration and cultivate practice? Answer: Previously, ordinary beings and followers of the two vehicles did not awaken to the ālaya[vijñāna], but merely gave rise to the aspiration and cultivated practice through the sustaining power of the differentiating empirical consciousness; because they did not penetrate the root, their approach to great bodhi was distant and indirect, hence it is called "gradual." These bodhisattvas, having realized the fundamental consciousness of ālaya, rely precisely on the sustaining power of this consciousness to give rise to the aspiration and cultivate practice; because they have penetrated the root, their approach to great bodhi is intimate and direct, hence it is called "swift." This distinguishes perfuming in terms of the mutual support of what is relied upon, not that they give rise to the aspiration independently, etc. This is as explained below under the section on the aspiration based on realization.
