Acceptance
Each day of human life contains joy and anger, pain and pleasure, darkness and light, growth and decay. Each moment is etched with nature's grand design - do not try to deny or oppose the cosmic order of things.
The Art of Peace, John Stevens, tr.,1992
Adversity
Be grateful even for hardship, setbacks, and bad people. Dealing with such obstacles is an essential part of training in the Art of Peace.
Ibid.
Appearance / Form
Do not get caught up with the form and appearance of a challenge. The Art of Peace has no form - it is the study of the spirit.
