成唯識論述記 6.454

6.454

述曰：五無輕安，體散動故。此師即說：十五界有漏，佛無無漏五識。若因若果，二位皆然。

The Commentary states: The five consciousnesses lack pliancy, because their nature is distracted and fluctuating. This master holds: The fifteen dhātus are sāsrava, and the Buddha does not possess anāsrava five consciousnesses. Whether in the causal stage or the fruition stage, both states are like this.
