唯識二十論述記 1.241

1.241

述曰：釋初二句頌。「似色現識」者，謂即眼識能現似色而轉之識，無實色故，名為「似色」。識現似色，故說眼識名似色現識。「從自種子緣合轉變差別生」者，從能生己識體之種，此種由境界等諸緣合已，異本相續，名為「轉變」。此了色識從自種子緣青、黃等，種種行相差別而生。

The commentary says: This explains the first two lines of the verse. 'The manifesting consciousness that resembles form' refers to the visual consciousness that operates being able to manifest resembling form; because there is no real form, it is called 'resembling form'. Consciousness manifests resembling form; therefore, the visual consciousness is called 'the manifesting consciousness that resembles form'. 'Arises with differentiation from its own seed through the transformation occurring upon the concurrence of conditions' means: from the seed capable of generating the substance of one's own consciousness, once this seed has combined with conditions such as the cognitive object, its continuum differs from its original state, which is called 'transformation'. This consciousness that discerns form arises from its own seed with differentiated modes of activity, taking blue, yellow, and so forth as conditions.
