2.54

七問：鈔中特陳理毒非性惡者，為顯思議耶？為顯不思議耶？若謂思議，非今所論；若不思議，一體三用那忽永殊？毒害之義唯屬事行，理性本無耶？

Seventh Question: Does the Chao's special assertion that principle poison is not nature-evil reveal the conceivable, or does it reveal the inconceivable? If you say it is the conceivable, it is not what is under discussion here; if it is the inconceivable, how could the three functions of the one substance suddenly be permanently different? Does the meaning of poisonous harm belong solely to phenomena and practice, being originally absent in the nature of principle?
