A teaching by the Great Zen Master Xuyun, delivered in 1947 at a middle school
In 1947, shortly after Japan’s surrender and withdrawal from China, the great Zen Master Xuyun (Empty Cloud) gave a profound speech at a middle school. The nation was still recovering from the devastation of war, and hearts were heavy with both relief and sorrow. With deep compassion, Master Xuyun used the timeless wisdom of the Buddha to explain the law of cause and effect (karma) — reminding people that wars do not arise by chance, but are the result of humanity’s collective actions.
He taught that true peace cannot be achieved through force or politics alone. Only by transforming our hearts and purifying our minds through virtue, compassion, and the practice of Buddhist teachings can we bring real and lasting peace to the world.
War does not arise by chance — it is the collective karma of all beings that brings it forth.
Dear friends, during the years of occupation, we endured immense suffering under the enemy’s oppression — our lives were steeped in water and fire, hardship and pain. Now that our nation has regained its light, we should feel endless gratitude and reflection. We must understand that the outbreak of war is not accidental; it is the result of the shared karma created by all individuals.
The ancient masters said, “If you wish to know the causes of your past lives, look at what you are experiencing in this life. If you wish to know the results of your future lives, look at what you are doing now.”
They also said, “Even after hundreds or thousands of eons, the karma one has created will not disappear. When the conditions ripen, the results will be experienced by oneself.”
When people lose their moral compass and commit all kinds of evil, they plant the seeds for calamities such as war, floods, fires, and famine. If we wish to change the will of Heaven and eliminate disasters, we must begin by transforming human hearts — by restoring virtue and morality. When everyone practices the Five Precepts and the Ten Good Deeds, cultivates upright minds and pure conduct, and lives with benevolence, trust, and righteousness, then the hearts of men and the will of Heaven will naturally align.
But if people persist in wrongdoing and refuse to repent, how can hostility and suffering ever be dissolved? The Buddha said, “The sea of suffering has no end, but when one turns around, there is the shore.” This means awakening from delusion and returning to goodness — the essential path to liberation.
We must truly believe in the law of cause and effect. It is not fiction but reality. If everyone understood that good deeds bring good results, and evil deeds bring suffering — that when one plants melons, one harvests melons; when one plants beans, one harvests beans — then no one would dare to act against conscience or break the law. Out of great compassion for all beings, Shakyamuni Buddha renounced his royal life and underwent arduous practice to save the world from ignorance and suffering.
If we understand the principle of cause and effect and wish to avoid future suffering, we must now create good causes. The hardships we experience today are the results of past evil actions. Therefore, we should now sow good seeds, and in time, we will naturally reap good fruits.
The scriptures speak of “Anuttara-samyak-sambodhi,” meaning “unsurpassed perfect enlightenment.” In its essence, it transcends the distinction of self and others — there is no “you” and “me.” But this state must be cultivated from one’s own heart. If our minds remain filled with greed, anger, and ignorance, unable to abandon all evil and practice all good, the barriers of self and ego become like iron mountains, preventing us from reaching the Pure Land or true harmony. This is the most crucial point — one we must all remember well.
The Sanskrit word “Buddha” means “the Awakened One.” Enlightenment has three aspects: awakening oneself, awakening others, and perfecting both understanding and conduct.
To awaken oneself is to realize that all experiences of good and evil, joy and suffering, arise from cause and effect. Once a person truly understands this, delusion fades, the four attachments dissolve, and one becomes enlightened.
To awaken others means recognizing that all living beings — whether born from the womb, from eggs, from moisture, or by transformation — all possess Buddha nature. They are called “sentient beings” only because they are deluded and unaware. We should therefore cherish and respect ourselves, and in keeping with the Buddha’s great vow of compassion and universal salvation, share these truths with others, guiding them out of the sea of suffering.
As stated in the Śūraṅgama Sūtra: “Regard all men as your fathers and all women as your mothers.” If we cultivate such deep reverence and love, especially for widows, orphans, and those who are lonely or destitute, and show them kindness and compassion through giving and aid, we can realize true equality and the ideal of great harmony.
To perfect both understanding and conduct means to live according to the Buddha’s teachings and precepts until one’s virtue and merit are complete. After the Buddha’s passing, he left behind the Three Baskets of Scriptures — Sutra, Vinaya, and Abhidharma — as our priceless raft to cross the sea of suffering. All the rules and precepts should be faithfully practiced. When one fulfills them completely, that is the perfection of wisdom and conduct.
Thus, the Buddha is the awakened one, while sentient beings are the deluded. The distinction between delusion and enlightenment marks the boundary between beings and Buddhas. To turn away from delusion and return to truth — that is awakening, and that is Buddhahood.
To further illustrate the law of karma, there is a story from one of Shakyamuni Buddha’s past lives.
Long ago, in the city of Rajagaha, there was a fishing village with a large pond. One year, a great drought struck, and the pond began to dry up. The villagers caught and ate almost all the fish, until only one giant fish remained, which was finally killed and eaten. Only one eight-year-old boy refused to eat the fish; he simply watched and laughed.
In his later life as the Buddha, King Prasenajit of Kosala, a devoted follower of the Buddha, married a princess of the Shakya clan, and they had a son named King Virudhaka. After ascending the throne, Virudhaka led his army to attack the Shakya capital of Kapilavastu and slaughtered all its inhabitants.
During that time, the Buddha suffered a severe headache for three days. His disciples begged him to use his powers to save the Shakya people, but he refused. Even when Maudgalyayana repeatedly pleaded, the Buddha said no. Maudgalyayana tried to rescue some survivors with his alms bowl, but when he put it down, all he found was a pool of blood.
When the disciples asked why, the Buddha revealed the cause: in a past life, during a great drought in Rajagaha, the villagers had killed and eaten the fish in that pond. The giant fish was reborn as King Virudhaka, and the villagers were reborn as the Shakyas who were killed. The young boy who merely watched and laughed was reborn as Shakyamuni Buddha himself. Because this karma had matured, the outcome was unchangeable.
The Buddha fully understood this karmic connection and taught it to his disciples as a warning. Chan Master Yuan Yun wrote in verse:
“For hundreds of years, the soup in your bowl
Is filled with deep hatred, hard to dissolve.
If you wish to know why wars arise,
Listen to the cries from the butcher’s gate at midnight.”
Reflect on this story and recite the verse, and you will awaken to the true causes of war and violence — and learn to guard your conduct with mindfulness.
If we wish to transform the world and move toward true harmony, everything must begin with our hearts. Students should study diligently, yet never forget the greater mission of saving the world. And the first step to saving the world is saving the heart — correcting one’s own wrong thoughts and firmly believing in the law of cause and effect, avoiding all evil paths.
By cultivating sincerity, righteousness, self-discipline, and harmony within the family, one can extend peace to the nation and the world. If all the people of every country sincerely believe in karma and practice the Eight Virtues and Ten Precepts, then oppression, violence, and wars will cease to arise. True peace, equality, and the Pure Land of Great Harmony will appear, free from the Five Defilements and all suffering.
