Answer: There is a fourfold proposition: First, constant but not deliberate: the eighth is constantly uninterrupted, but does not deliberately ponder self and dharmas. Second, deliberate but not constant: this is the sixth; although it deliberately ponders, it is not constant, and therefore is not named manas. The first five are neither: neither constant nor deliberate. The seventh subsumes both, being both constant and deliberate; therefore, it alone is named manas.
