此但遮實，非是緣彼離識外境智之所得，而不表是緣不離識現量智得，以彼實句本無體故。又識內境非皆現量智之所得。

This merely negates that substance is apprehended by a cognition that takes as object an external entity separate from consciousness; it does not express that it is apprehended by a direct perceptual cognition that takes as object what is not separate from consciousness, because that category of substance intrinsically lacks substantial reality. Furthermore, not all internal objects of consciousness are apprehended by direct perceptual cognition.
