俱舍論記 27.138

27.138

「若一化主至亦容有別」者，釋第七、第八句。餘二乘、異生定非自在，而不能令一語一默，要語皆同。佛定自在，或時皆同、或復能令一語一默。准《婆沙》文，乃至諸佛化主及所化能發語心，前後各別，於中迅速謂語俱時。理實前後，言一心發，謂一相續心。

"If a single master of apparitions ... there may also be differences": this explains the seventh and eighth lines. The absorptions of other persons of the two vehicles and ordinary beings are not sovereign, and thus they cannot make one speak and another remain silent; necessarily, all their utterances must be identical. The Buddha's absorption is sovereign: sometimes they are all identical, and at other times he can make one speak and another remain silent. According to the text of the *Mahāvibhāṣā*, even for the various Buddhas, the minds capable of emitting speech in the master of apparitions and in the apparitions are distinct before and after; in the rapid [succession] between them, the speech is thought to be simultaneous. In reality, they are before and after; the statement that it is emitted by one mind means one continuous mental stream (saṃtatāna).
