The Causeless Sorrow: A Psychological Cancer That the Buddha’s Teachings Can Heal

Have you ever sat alone, watching a river flow, only to feel a sudden, heavy sadness rise within your heart without knowing why? Perhaps it was just a fleeting moment of melancholy that passed. But if that sadness lingers, refusing to leave, and you find yourself feeding it with thoughts until it grows larger, this is a sign of a condition the modern world calls depression. Venerable Thich Chan Quang describes this state as "cancer of the mind."

## Depression: The Invisible Cancer of the Mind

During a dharma talk on Vesak Day, Venerable Chan Quang shared a haunting story. A co-pilot, suffering from depression, crashed his plane into a mountain, taking the lives of one hundred and fifty people. There was no logical reason, no conflict, only a seemingly causeless sorrow that had infiltrated and consumed his entire being.

The Venerable stated firmly, "Depression is a natural psychological illness where a person experiences sadness without finding any cause."

There is a subtle difference between normal sadness and clinical depression. Ordinary people experience transient grief, while those with depression endure persistent sorrow and actively create reasons for it. As the Venerable explained, "You think wrongly to make yourself sad again and again. It is strange. You continue thinking to keep the sadness going. That is depression."

This is a form of psychological cancer. Physical cancer can be seen, imaged, and surgically removed, but psychological cancer is invisible. It does not hurt the body, yet it erodes spiritual life, causing people to gradually lose their desire to live.

## When Sadness Becomes a Habit

Venerable Chan Quang offered a very ordinary example. While sitting by the river, a baseless sadness arises. Seeing a piece of trash float by, a depressed person begins to speculate: "Life is already sad, and now someone throws trash into the river. How thoughtless are people?" Then, seeing a fishing boat, they think, "People struggle so hard to survive, killing other beings; life is truly weary." In this way, sadness is "watered" by negative, accumulating thoughts, becoming a storm that never settles.

We are witnessing a pandemic of depression in our time. Many young, talented, loved, and successful people still commit suicide due to inexplicable boredom and despair. The Venerable emphasized, "Family members search for the cause, asking what they are sad about, but they cannot find it. Their partner is still there, sending loving messages; teachers still value them; they study well and fulfill their duties, yet the waves of sadness roll on endlessly."

This indicates a self-generated sorrow, not caused by external circumstances. If not intervened in time, this sadness becomes a psychological tumor, silently growing and stealing away life.

## The Buddha’s Teachings: A Medicine to Halt the Disease

What is precious is that the Buddha’s teachings offer a method to transform this issue at its root. Practitioners following the Dharma are not permitted to dwell in distress, for that is characteristic of ordinary people. Instead, practitioners must cultivate equanimity and ease. The Venerable said, "Even when humiliated to the utmost limit, one remains calm, without anger or resentment, and without sadness or hatred."

He told a story of a poor monk who possessed a golden staff. His disciple secretly stole it. When the disciple came to confess, filled with guilt, the master simply said, "Before we had this golden staff, teacher and student lived just fine." The disciple suddenly awakened, recognizing the profound peace of his master. This is the power of practice.

It is crucial not to let trivial matters—such as words, ego, or jealousy—destroy your inner peace. The Dharma teaches us to be unmoved by the eight worldly winds: gain and loss, praise and blame, fame and disrepute, pleasure and pain. We must maintain a mind that does not waver.

## Noble Sadness: The Great Compassion

Thus, Buddhist practitioners do not grieve over personal affairs, but they do feel sorrow for the suffering of all sentient beings. This is not depression; it is great compassion. The Venerable explained, "Bodhisattvas feel deep anguish for the suffering of beings; we call this knowing how to be sad. Yet, that sadness remains serene and quiet. They still smile, still meditate, and still practice."

The sadness of a Bodhisattva is accompanied by infinite love. The Buddha once illustrated this: if a stranger from a distant village dies, we feel nothing; if a neighbor dies, we feel slight sadness; if a spouse dies, we feel extreme grief. Suffering stems from attachment and love. Practitioners love all beings, so they carry a great sorrow—but it is a peaceful sorrow, full of compassion.

In contrast, a depressed person feels sad without loving anyone, not even themselves or life itself. This is a soulless sadness; it is an illness.

## Other Psychological Cancers Lurking Around Us

Beyond depression, Venerable Chan Quang identified other psychological illnesses that often go unnoticed.

Pathological jealousy occurs when a wife returns home early from the market, and her husband immediately suspects an affair. Every word and gesture is distorted into evidence of betrayal.

Paranoia involves assuming the worst of everyone. Seeing someone diligently attending the temple, one might say, "They go to the temple to seduce the teacher." Seeing someone sit solemnly, one might accuse them of "acting."

Kleptomania affects some famous and wealthy individuals who feel compelled to steal small items from stores. They seek the thrill and the benefit of getting something for free.

Arrogance manifests as always believing oneself superior to others and criticizing everything. The Venerable warned, "Always consider yourself like grass or dust to block this disease."

Sexual addiction crosses legal and moral boundaries to satisfy desires, leading to imprisonment and broken relationships.

Delusion involves imagining oneself as a prime minister, a saint, or an enlightened Zen master. "This delusion burns up all your merit," the Venerable said.

All these are forms of "psychological cancer" that need to be recognized and treated through the Buddha’s teachings, humility, and mindfulness.

## Return to Peaceful Mind

Reading this, you may ask: How can we avoid these cancers? Venerable Chan Quang taught a simple method: do not nurture causeless sadness. Whenever you feel sad, reflect on where it comes from. If it is not for the benefit of sentient beings or out of genuine love, then it is an illness. Cut it down with the equanimity of a Buddhist child.

More importantly, cultivate the mind of great compassion. When great compassion arises, every feeling of sadness transforms into motivation for wholesome action. Return to the Buddha’s teachings, to ethics, and to humility. These are the healing medicines for all psychological cancers.

Amidst a life full of suffering, be a person who is calm, optimistic, and compassionate. This is the path the Buddha taught—the path of happiness and liberation.
