The Question of the Location of the Manas

Question: When consciousness arises from the contact of faculty and sense-object, and the mind consciousness does not arise anywhere other than at the supreme faculty, can we then conclude that the manas is located at the supreme faculty?

Answer: The manas is not entirely located at the supreme faculty either. The manas abides throughout the entire brain. The manas does not depart from the supreme faculty, yet it is not located solely at the supreme faculty. Beyond the supreme faculty, there are mental sense-objects, and the manas must discern them. Whenever the eighth consciousness manifests dharmas, the manas necessarily relies on the eighth consciousness to take them as object and discern them.
