大乘起信論別記 1.170

言「業識根本熏習」者，以此業識熏習無明，迷於無相故，起能見及境界相，見相相續生死不絕，此見及相在梨耶識。彼三乘人雖離分別事識分段繫業麁苦，猶受梨耶微細行苦，故言三乘生滅苦也。

"Fundamental perfuming of the karmic consciousness" means: because this karmic consciousness perfumes avidyā, being confused about signlessness, it gives rise to the characteristics of the capacity to see and objects; seeing and characteristics continue without end in saṃsāra. This seeing and characteristics exist in the ālayavijñāna. Although those of the three vehicles are free from the coarse suffering of the karma of fragmented [birth and death] bound to the consciousness that discriminates objects, they still undergo the subtle suffering of conditioning of the ālayavijñāna; therefore it says, "the suffering of arising and ceasing of the three vehicles."
