大乘起信論別記 1.185

1.185

言「業識」者，義如前說。然餘處說，地前所見，名反化身，地上所見，名受用身。為異已證未證故，今此中說凡夫二乘所見，名為應身；十解初心以下所見，名為報身，為明菩薩深信唯識順業識義，不計外來不同凡小故。又復此中，就此三賢菩薩依三昧心所見妙相故，屬報佛攝。餘經論中，約此菩薩散心所見麁相故，屬化身也。餘文分明故則可知。

Regarding "karmic consciousness," the meaning is as explained before. However, in other places it is taught that what is seen prior to the stages is called the created transformation body, while what is seen on the stages is called the saṃbhogakāya. In order to distinguish between those who have realized and those who have not realized, here it is stated that what is seen by ordinary beings and the two vehicles is called the nirmāṇakāya, whereas what is seen from the initial mind of the ten understandings onward is called the saṃbhogakāya, so as to clarify that bodhisattvas deeply believe in consciousness-only and accord with the meaning of karmic consciousness, not imagining it to come from outside, unlike ordinary beings and followers of the Hinayana. Furthermore, here, because it pertains to the sublime characteristics seen by these bodhisattvas of the three [stages of] worthies relying on the mind of samādhi, it is subsumed under the saṃbhoga Buddha. In other sūtras and treatises, referring to the coarse characteristics seen by these bodhisattvas with a scattered mind, it is subsumed under the transformation body. The rest of the text is clear, and can thus be known.
