The eight perceptions are fundamentally unity, opposed by the 唯識 school with the doctrine 八識體別 that they are fundamentally discrete.

A Dictionary of Chinese Buddhist Terms, William Edward Soothill and Lewis Hodous

所有八識的體性都是一體，這是唯識宗的異義。

陳義孝編, 竺摩法師鑑定, 《佛學常見辭彙》

（雜語）對八識體別而言。謂諸八識之體性，悉為同一也。出於無性之攝論四卷，世親之攝論三卷，為一類之菩薩所主張者，唯識宗之異義也。
