大乘起信論裂網疏 4.73

4.73

同一味者，同無漏味也。同一真者，如如及如如智，即是一真法界也。離分別相者，非諸凡夫、二乘、權位菩薩所能測識也。無二性故者，唯是圓成實性所攝也。

"The same single flavor" means the same untainted flavor. "The single truth" means that tathatā and the wisdom of tathatā are precisely the one true dharmadhātu. "Free from conceptual marks" means it is not something that ordinary beings, the two vehicles, or bodhisattvas of provisional stages can fathom or know. "Because they lack a dual nature" means it is subsumed solely under the perfected nature (pariniṣpanna-svabhāva).
