大乘起信論裂網疏 5.70

5.70

即《華嚴》初發心時便成正覺之義也。分破無明，分證真如，故云少分見佛法身。既見法身，便能八相成道，所謂清淨妙法身，湛然應一切也。八相開合出沒不同，並是隨機所見，不必約此以判佛之權實，以所證法身非有權實數量可思議故。

This is precisely the meaning in the Avataṃsaka of 'upon the initial generation of the mind, one immediately achieves correct awakening.' Partially breaking through ignorance and partially realizing tathatā, it therefore says 'attaining a partial vision of the Buddha's dharmakāya.' Having seen the dharmakāya, one can immediately accomplish the Way through the eight aspects, which is the so-called pure, wondrous dharmakāya serenely responding to all. The opening, joining, appearing, and disappearing of the eight aspects are not identical, and are all seen in accordance with the faculties [of beings]; one need not judge the provisional or real of a Buddha based on this, because the dharmakāya realized is not something whose provisionality, reality, or quantity can be conceived.
