成唯識論了義燈 1.32

1.32

答：為根熟惠悟既通故。為顯說三乘所觀空有諸法，云為一切。《般若經》中，雖有三乘，各各得益，未分明說法非空有，故屬第二。若約頓悟，可立一時。

Answer: Because the faculties are ripe and the wisdom and awakening are pervasive. Because it clearly teaches the dharmas of emptiness and existence observed by the three vehicles, it is said to be for all. In the Prajñāpāramitā-sūtras, although the three vehicles each attain their own benefits, it does not yet clearly explain that dharmas are neither empty nor existent; therefore, it belongs to the second [period]. If in terms of sudden awakening, a single period may be established.
