成唯識論演祕 4.207

4.207

此顯前相具二支故成所緣緣，前相體有名之為緣，識帶彼相成所緣義。故《觀所緣論》云：所緣緣者，謂能緣識帶彼相起，及有實體令能緣識託彼而生。

This reveals that because the preceding objective aspect possesses the two branches, it constitutes an objective condition: the preceding objective aspect having real existence is called 'condition', and the consciousness bearing its aspect constitutes the meaning of 'object'. Thus the Ālambanaparīkṣā says: 'An objective condition means that the cognizing consciousness arises bearing that aspect, and there is a real entity that enables the cognizing consciousness to be produced relying on it.'
