金光明經玄義 1.36

1.36

Question: As the sūtra states, 'Rely on wisdom, not on consciousness.' Since you speak of three consciousnesses, how can they be relied upon? Answer: When the sūtra says not to rely on consciousness, it refers to the consciousness of saṃsāra; here it is not so. When we speak of relying on consciousness here, it is another name for wisdom, called pure consciousness. Furthermore, prior to the path it is generally called consciousness; after the path its basis is transformed, which is wisdom, though this is not yet fully explained.
