There is more information available on this subject at Zen on the English Wikipedia.

Zen is a mental and spiritual type of thought and practice, that was practiced in various ways by Spartan-IIs to improve their skills in the 26th century.[1]

Usage and examples[edit]


Linda-058 is "icy cold state of Zen no-thought" whenever she is sniping in combat.[2][3] Kelly-087 practices Zen arts on a daily basis, including Zen twitch response drills to keep her reflexes sharp.[1] Naomi-010 thought she sounded a bit zen when she said "You have to know how much gas to pour on a fire" to Vasily Beloi,[4] a thing Beloi later thought about when Serin Osman drip fed the Servants of the Abiding Truth supplies.[5]

Artificial intelligence[edit]

UNSC Artificial Intelligence constructs are fascinated by Zen philosophy because of their natural creativity and limited life span. Dr. Catherine Halsey, designer of many of these AIs, is sometimes able to manipulate them by presenting them with Zen philosophies.[6]


Some Sangheili similarly follow a form of Mendicant in the same fashion that the Spartans casually perform Zen.
