The Eyes of a Compassionate Heart

A physician once flew into a rage because a patient broke her promise, causing a woman to become blind again. The karmic consequence of that anger followed him through many lifetimes, until even the diligent monk of a later age still had to repay that karma with his eyes.

In a quiet forest, beneath an ancient tree, an elderly monk sat silently on a rock. His eyes were swollen and red, and he could no longer see. Beside him, a young novice was trying to wipe away the tears streaming down the old monk's wrinkled face. Evening had come, and darkness was slowly falling, yet within the monk's heart there remained a faith that nothing could shake.

His name was Chūla-panthaka, one of the most diligent elders among the Buddha's disciples. His family was wealthy, but after meeting the Buddha, he gave up all his possessions and ordained to devote himself to practice. He was famous for his vow never to lie down, keeping only three postures—walking, standing, and sitting—so that he could remain ever wakeful. But because he observed this practice too strictly, his eyes began to ache. The other monks urged him to lie down and rest, but he only shook his head: "I have made a vow. I cannot break it."

One day, a skilled physician from the region came to treat him. After examining him, the physician said: "This illness is not serious, but medicine must be poured into the nose so it can flow upward to the eyes. Tonight, before you sleep, please apply this medicine." The monk accepted the bottle of medicine, but when night fell, he remained seated in meditation and never lay down. The next morning, the physician returned, saw that the monk's eyes were still swollen and red, and asked: "Did you lie down?" The monk remained silent. The physician asked again and again, until at last he learned the truth. He sighed: "If you do not lie down, the medicine cannot flow upward to your eyes. There is nothing more I can do." With that, he left. And so, the monk's eyes went completely blind.

When the other monks completed the rains retreat, they led him back to the monastery. His younger brother, hearing the news, sent his son to bring the elder home. The boy guided the monk with a stick, but along the way, he met a girl and abandoned the old monk, leaving him sitting alone in the middle of the forest. As darkness deepened, the blind monk sat by himself, not knowing where to go. Suddenly, a stranger appeared and spoke in a warm voice: "Venerable sir, may I have your permission to guide you back to the monastery?" It was Sakka, the king of the devas, who had been moved by the monk's diligent practice and had descended to earth in human form. Thanks to this stranger's guidance, the monk returned safely to the monastery.

The monks were puzzled and asked the Buddha: "World-Honored One, why would an elder who practiced so diligently and so sincerely become blind?" The Buddha looked around and then told a story from the distant past: "Long ago, there was a poor woman whose husband had died early, leaving her to raise three children alone. She suffered from an eye disease and was nearly blind. A physician came to treat her, and she said: 'I have no money, but if you heal my eyes, my three children and I will serve you for the rest of our lives in gratitude.' The physician agreed and cured her eyes. But when her sight returned, she broke her word and refused to serve him. The physician was furious and thought: 'This woman is so heartless. I saved her eyes, and now she deceives me.' In his rage, he applied poison to her eyes, leaving her blind forever."

The Buddha paused, and his voice grew deep: "That physician of long ago was none other than Elder Chūla-panthaka. Because of that anger, he had to endure the consequence of blindness for many lifetimes. Even though he has now encountered the true Dharma and practices diligently, the old karma cannot be erased. It must be repaid in full."

Hearing this, the monks shuddered. A small burst of anger, one impulsive act—and the price was his eyes, paid across so many lifetimes. The Buddha looked at them all and said slowly: "Mind leads all things. Mind is the master that creates them. If one speaks or acts with an impure mind, suffering follows, just as the wheel follows the ox that draws the cart."

From then on, the monks understood more deeply the terrifying power of the mind. A single angry thought can create karma so heavy that it follows one not for a single life, but for many. And they came to appreciate all the more the Buddha's teaching: always keep the mind pure, for happiness or suffering—all of it is created by the mind.

The Meaning of the Story

The profound lesson that Venerable Thích Chân Quang wished to convey is this: the mind is the root of every action. A moment of anger, however small, if allowed to control us, will lead to actions that create bad karma, with consequences that stretch across many lifetimes. Conversely, if we keep the mind pure, happiness will follow us like a shadow follows its form. Therefore, each of us must learn to master our own mind, especially by controlling anger and impure thoughts.
