成唯識論了義燈 4.5

Question: Since conceptualization has the formulation of conventional designations as its activity, why is it not the cause of speech? Answer: According to what the Miśrakābhidharma-samuccaya says, it is the cause of subsequent expression, not the preparation for speech. It is because of conceptualizing the image of an object that conventional designations are established; its functional capacity is remote. Investigation and examination (vitarka and vicāra) have a direct function, as they directly initiate speech, and are therefore said to be the formations of speech.
