As we continue moving our awarness inward we will come to the buddhi the highest faculty of knowledge that just seems to know things. This is the silent knower who doesn’t argue because it doesn’t have to; the buddhi just knows. The buddhi is always endowed with truth; not necessarily the highest truth, but certainly what is true for the individual soul.This is one of the key differences between the buddhi and the manas. The manas is always seeking truth, usually from the outside world, while the buddhi silently knows the truth emanating from the individual soul.
