3.574

述曰：謂若是觸等緣似種相，名一切種，即是第四緣境之門。在第三門一切種後，執受處中方應相例，如何於前一切種中乃例緣境。

The Commentary states: That is, if it were that contact and so forth take the marks of semblance-seeds as cognitive objects and are called 'possessing all seeds', this would be the fourth gateway, of taking objects as cognitive conditions. Only after the third gateway, 'possessing all seeds', in [the discussion of] appropriating and resting-place (upādāna-sthāna), should they be analogised; why analogise cognitive objects earlier, within 'possessing all seeds'?
