Buddhism is not one. The teaching of Buddhism is many. When Buddhism enters one country, that country always acquires a new form of Buddhism. Buddhism, in order to be Buddhism, must be suitable, appropriate to the psychology and the culture of the society that it serves.

1. Do not be idolatrous about or bound to any doctrine, theory, or ideology, even Buddhist ones. All systems of thought are guiding means; they are not absolute truth. If you have a gun, you can shoot one, two, three, five people; but if you have an ideology and stick to it, thinking it is the absolute truth, you can kill millions.
2. Do not think that 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.
4. Do not avoid contact with suffering or close your eyes before suffering. Do not lose awareness of the existence of suffering in the life of the world. Find ways to be with those who are suffering by all means, including personal contact and visits, images, sound. By such means, awaken yourself and others to the reality of suffering in the world.
5. Do not accumulate wealth while millions are hungry. Do not take as the aim of your life fame, profit, wealth or sensual pleasure. Live simply and share time, energy and material resources with those who are in need. In the context of our modern society, simple living also means to remain as free as possible from the destructive social and economic machine, and to avoid stress, depression, high blood pressure and other modern diseases.
6. Do not maintain anger or hatred. As soon as anger and hatred arise, practice meditation on compassion in order to deeply understand the persons who have caused anger and hatred. Learn to look at other beings with the eyes of compassion.
7. Do not lose yourself in dispersion and in your surroundings. Learn to practice breathing in order to regain composure of body and mind, to practice mindfulness, and to develop concentration and understanding. Live in awareness.
8. Do not utter words that can create discord and cause the community to break. Make every effort to reconcile and resolve all conflicts, however small.
9. Do not say untruthful things for the sake of personal interest or to impress people. Do not utter words that cause division or hatred. Do not spread news that you do not know to be certain. Do not criticize or condemn things that you are not sure of. Always speak truthfully and constructively. Have the courage to speak out about situations of injustice, even when doing so may threaten your own safety.
10. Do not use your religious community for personal gain or profit, or transform your community into a political party. A religious community should, however, take a clear stand against oppression and injustice, and should strive to change the situation without engaging in partisan conflicts.
11. Do not live with a vocation that is harmful to humans and nature. Do not invest in companies that deprive others of their chance to life. Select a vocation which helps realize your ideal of compassion.
12. Do not kill. Do not let others kill. Find whatever means possible to protect life and to prevent war.
13. Possess nothing that should belong to others. Respect the property of others but prevent others from enriching themselves from human suffering or the suffering of other beings.
14. Do not mistreat your body. Learn to handle it with respect. Do not look on your body as only an instrument. Preserve vital energies (sexual, breath, spirit) for the realization of the Way. Sexual expression should not happen without love and commitment. In sexual relationships be aware of future suffering that may be caused. To preserve the happiness of others, respect the rights and commitments of others. Be fully aware of the responsibility of bringing new lives into the world. Meditate on the world into which you are bringing new beings.
