維摩經略疏 2.103

2.103

問：何不以四種緣集對四土明四種眾生類耶？答：一往似便，於理有妨，無別自體法界異無為也。得失之事，至〈問疾品〉當更分別。若還約無為分出二種，是則無失，必應須開。但約四教開四眾生，此即便也。

Question: Why not match the four kinds of accumulation through causes to the four lands to explain four kinds of categories of living beings? Answer: At first glance it seems convenient, but it conflicts with the principle; there is no separate self-nature of the dharma realm distinct from the unconditioned. The matter of advantages and disadvantages will be further distinguished when reaching the chapter "Inquiring after the Illness". If one still divides two kinds based on the unconditioned, then there is no error, and it must indeed be unfolded. Merely unfolding four kinds of living beings according to the four teachings is what is convenient here.
