釋摩訶衍論 3.4

3.4

本曰：所言覺義者，謂心體離念相。離念相者，等虛空界無所不遍法界一相，即是如來平等法身。依此法身說名本覺。何以故？本覺義者對始覺說，以始覺者即同本覺。始覺義者，依本覺故而有不覺，依不覺故說有始覺。又以覺心原故名究竟覺，不覺心原故非究竟覺。

The root treatise states: The so-called 'meaning of awakening' means that the essence of the mind is free from the characteristics of thoughts. Being free from the characteristics of thoughts is equal to the realm of space, all-pervading, of a single characteristic of the dharmadhātu, which is the equal dharmakāya of the Tathāgata. Dependent upon this dharmakāya, it is named original awakening. Why is that? The meaning of original awakening is spoken of in contrast to initial awakening, because initial awakening is identical to original awakening. The meaning of initial awakening is that dependent upon original awakening there is non-awakening, and dependent upon non-awakening it is said that there is initial awakening. Furthermore, because of awakening to the source of the mind, it is called ultimate awakening; because of not awakening to the source of the mind, it is not ultimate awakening.
