說無相取不取相故者。即瑜伽論七十三說。取有三種。一有言有相取。謂言說隨覺者取。二無言有相取。謂言說隨眠者取。三無言無相取。謂是於言說離隨眠者取。此正體智當第三取。說無相故便無相分。說取言故便有見分。下後智中有二說字。應知皆是瑜伽論說。

Regarding "It is said that signless apprehension does not apprehend signs": this is stated in fascicle 73 of the Yogācārabhūmi: There are three kinds of apprehension. 1. Apprehension with words and with signs, which is apprehension by those whose discursive speech is actively awake. 2. Apprehension without words and with signs, which is apprehension by those whose discursive speech is latent. 3. Apprehension without words and without signs, which is apprehension by those who are free from the latencies of discursive speech. This fundamental wisdom corresponds to the third apprehension. Because it is described as "signless", it lacks an objective aspect; because the word "apprehension" is used, it possesses a subjective aspect. Below, in the discussion of subsequent wisdom, the word "said" occurs twice; it should be known that both are citations from the Yogācārabhūmi.
