In my opinion that language is a way of communicating what is explained in MN 1, which points out the difference between "perceiving [x] as [x]", resulting in "conceiving" regarding that. While the goal is "directly knowing" in order to "fully understand it"
"When one thing is practiced & pursued, ignorance is abandoned, clear knowing arises, the conceit 'I am' is abandoned, latent tendencies are uprooted, fetters are abandoned. Which one thing? Mindfulness immersed in the body." -AN 1.230
