13.139

泰云：了別者，辨賴耶識於外器相能了別，即釋章明中了別語依止緣內等者，即賴耶識一分緣內執受種義，有一分了別外器世界相，於外器界一分，了別賴耶識依止彼緣內種分之識而外變為外器之相，恒時無斷故，燈焰生時喻彼外器中能了別，膏如執受種，炷喻賴耶識，光喻外器相，是即此外器了別依止彼種子及依止賴耶而外變器相，更不別解其能了別。

Tai says: 'Discerning' means explaining that the ālayavijñāna is able to discern the aspect of the external vessel; that is, explaining the word 'discerning' within the passage. 'Relying upon cognizing the internal,' and so forth, means that one part of the ālayavijñāna has the function of taking internally appropriated seeds as object, and one part discerns the aspect of the external vessel world. With respect to the part [discerning] the external vessel world, the discerning ālayavijñāna relies on that consciousness's part which takes internal seeds as object and externally transforms into the aspect of the external vessel constantly and uninterruptedly. Thus, when the lamp flame arises, it illustrates that within the external vessel, which can discern; the oil is like the appropriated seeds; the wick illustrates the ālayavijñāna; the light illustrates the aspect of the external vessel. That is, this discerning of the external vessel relies upon those seeds and relies upon the ālaya to externally transform into the aspect of the vessel, without providing any further distinct explanation of what can discern.
