Enlightenment
To attain enlightenment regarding something means that we have completely made it our own. For reference, enlightenment is entirely different from understanding. For instance, there is a phrase that we should regard as the most fundamental guide in life: "Confirm." If someone comes to attain enlightenment regarding this phrase through cause and effect, whenever they encounter objects or facts they are not fully aware of, they would spontaneously practice the act of confirming them.
