大乘起信論廣釋卷第三．四．五 4.38

4.38

論。以因緣至成自然業　釋曰。此顯證理。因謂無明。緣謂妄境也。心相謂即麁細染心。此皆盡故心體轉依。名得涅槃成自然業。轉依有二。一轉顯。即由了因心體顯故名得涅槃。二轉得。即由生因心用起故成自然業。初即正體照寂之惠。後即後得寂照之智。菩提涅槃二勝果也。

[Treatise:] Because the causes and conditions [...] spontaneous activities are accomplished. / [Commentary:] This reveals the realized principle. "Cause" refers to avidyā; "condition" refers to deluded objects. "Marks of the mind" refers to the coarse and subtle defiled minds. Because these are all exhausted, the substance of the mind undergoes the revolution of the basis (āśrayaparivṛtti), which is called attaining nirvāṇa and accomplishing spontaneous activities. The revolution of the basis is of two kinds: first, revolution through revelation, in which the substance of the mind is revealed through the revealing cause, called attaining nirvāṇa; second, revolution through acquisition, in which the activity of the mind arises through the productive cause, accomplishing spontaneous activities. The former is the fundamental wisdom that shines upon quiescence; the latter is the subsequent cognition whose quiescence shines: these are the two superior fruits of bodhi and nirvāṇa.
