俱舍論記 29.149

29.149

「若爾世尊至可能遍知」者，犢子部難。若無我者，世尊應非是一切智。無心、心所能知一切法，乃至無我觀亦不知自性、相應、俱有法。剎那、剎那前後不同，異生滅故。若許有我不剎那滅，多時經停可能遍知。

"If so, the World-Honoured One... would be able to know everything": the Vātsīputrīyas object. If there is no self, the World-Honoured One would not be omniscient. No mind or mental factor can know all phenomena; even the contemplation of not-self does not know its own nature, its associated dharmas, or its co-existent dharmas. Moment by moment, preceding and succeeding are different, as they arise and cease separately. If one accepts that there is a self that does not perish moment by moment, enduring for a long time, it would be able to know everything.
