Knowledge can be useful as a tool and reference point, but there is so much more than just knowledge alone. All the masters knew there was more — in simplicity. People who seek after knowledge, only for the sake of knowledge, become trapped in a process where the means becomes the end.

Instead, they spend their lives trying to learn everything that exists beyond them, in the hope of finding the truth that already lies within.
