唯識二十論述記 1.34

1.34

此中意說：謂今此論，施設大乘中所立三界法皆唯有識，問：離繫法為唯識不？答：此亦唯識。問：何故此中但言「三界」？答：且舉異生所成妄法唯有識理，但言「三界」，非無漏法無唯識義，此為理解，或由教故。

The intention here is: namely, that this treatise posits that the phenomena of the three realms established in the Mahāyāna are all consciousness-only. Question: Are unconditioned phenomena also vijñapti-mātra or not? Answer: These are also vijñapti-mātra. Question: Why is it that here only 'the three realms' are mentioned? Answer: Temporarily citing the principle that the false phenomena formed by ordinary beings are consciousness-only, it merely speaks of 'the three realms'; it is not that pure phenomena lack the meaning of vijñapti-mātra. This is understood through principle, or by virtue of the teaching.
