楞伽阿跋多羅寶經註解 1.495

1.495

此言藏識微細行相，唯有諸佛及登地菩薩能知究竟邊際，一切二乘、外道所得三昧之力皆不能知。

This states that as for the subtle mode of activity of the storehouse consciousness, only the Buddhas and the bodhisattvas who have ascended the bhūmis can know its ultimate limit; the power of samādhi attained by all of the two vehicles and the tīrthikas is entirely incapable of knowing it.
