瑜伽師地論略纂 11.11

11.11

論云「又所化身，若自若他，或似不似，唯能化作與根相似、根所依處，而非實根」者，以根用不可化作故，眾生界有增過故，不可似用。其根所依處，即四五塵內外界，故可化得似。

The treatise states: 'Furthermore, the manifested body, whether of oneself or another, whether similar or dissimilar, can only be manifested to resemble the faculties and the bases of the faculties, but is not the real faculties.' This is because the functioning of the faculties cannot be manifested, and because there would be the fault of an increase in the realm of sentient beings; hence their function cannot be simulated. The bases of those faculties are simply the internal and external realms of the four or five dusts; therefore they can be manifested to resemble them.
