摩訶止觀 5.63

5.63

答：十境不同，即別義也。復有亦通亦別：陰是受身之本，又是觀慧之初，所以別當其首，此一境亦通亦別。後九境從發異相受名，但得是通、是別，不得是亦通亦別也。

Answer: The ten realms being different is precisely the specific meaning. Furthermore, there is that which is both general and specific: the aggregates are the root of receiving a body and also the beginning of contemplative wisdom, which is why they specifically take the lead; this single realm is both general and specific. The latter nine realms receive their names according to the distinct characteristics that arise; they can only be general or specific, but cannot be both general and specific.
