The most difficult door to open is the entrance to an ignorant mind.

Teach the ignorant. Study the wise. Avoid the foolish. Embrace the enlightened.

Knowledge is the path, understanding is the way, wisdom is the highway, and enlightenment is the destination.

Esteem intelligence, cherish knowledge, and value understanding, but trust wisdom.

To be knowledgeable, sit before scholars; to be wise, sit before life.

Ignorance shuts the mind’s door tight; wisdom swings it wide open.
