故彼下。兩文皆證顯色身義耳。然此一段疑中，從微至著明真應二身，總有六重：一、明佛相非相，二、明佛相非即如來，三、明一切相皆非相，四、明一切相非相皆如來，五、明唯證相應無佛可見，六、明無相之相是真色身。然此六重，前前則淺、後後轉深，文不累書理即頓現，達者所見必須一時無前後耳。

Regarding "Therefore that..." below: both passages corroborate and reveal the meaning of the physical body. Now, within this doubt, clarifying the true and responsive bodies from subtle to prominent has six levels in all: first, clarifying that the Buddha's marks are non-marks; second, clarifying that the Buddha's marks are not immediately the Tathāgata; third, clarifying that all marks are non-marks; fourth, clarifying that all marks being non-marks is everywhere the Tathāgata; fifth, clarifying that only in corresponding realization is there no Buddha to be seen; sixth, clarifying that the mark of marklessness is the true physical body. In these six levels, the earlier ones are shallower and the later ones become progressively deeper. Although the text cannot be written down all at once, the principle manifests suddenly; what the realized person sees must be simultaneous, without before or after.
