“If we are not able to be peaceful and happy in every step, a peace march is not a peace march.”

Thay taught us that there is no conflict between the most effective political activism and the personal practice of dwelling in peace; in fact, these are one and the same.
From the Fourteen Precepts
2. Do not think the knowledge you presently possess is changeless, absolute truth. Avoid being narrow-minded and bound to present views. Learn and practice non-attachment from views in order to be open to receive others’ viewpoints. Truth is found in life and not merely in conceptual knowledge. Be ready to learn throughout your entire life and to observe reality in yourself and in the world at all times.
3. Do not force others, including children, by any means whatsoever, to adopt your views, whether by authority, threat, money, propaganda, or even education. However, through compassionate dialogue, help others renounce fanaticism and narrowness.
