Lyceum of Yggdrasil
Emotion, yet peace.
Ignorance, yet knowledge.
Passion, yet serenity.
Chaos, yet harmony.
Death, yet the force.
— The Jedi Code (Universalist Version).
You have been taught to avoid arrogance. It is a grave sin you are told.
You are also told the the Force that hold together, penetrates, and connects the entirety of existence has the same petty foibles as you do.
To, believe this is arrogance. Believing that there is a Dark Side of the force, is itself a grave sin.
