Fierce Bacteria: The Hidden Teachers
According to Venerable Thích Chân Quang, fierce bacteria are not enemies but hidden teachers reminding humanity to live in harmony with nature.

At Tet, we often wish each other luck and peace. But have you ever paused and wondered: why does the world keep seeing more and more fierce bacteria that give humanity such headaches? HIV, SARS, bird flu, mad cow disease... Where do they come from? Could they be merely random disasters?
Bacteria: Enemy or Teacher?
In a dharma talk given on the third day of Tet, Thầy Thích Chân Quang shared that he himself had contracted the H5N1 bird flu in 2004, nearly lost his life, and needed more than a year to recover. From that experience, he realized that fierce bacteria are not only enemies of humankind, but also hidden teachers.
Do not think of HIV merely as the shared sorrow of humanity—beware of seeing it as a teacher of humanity. We should not think of bird flu as an enemy... No, it is another teacher of ours, a teacher who teaches a different subject.
In Buddhism, illness is one of the eight kinds of suffering (dukkha) that no one can escape. But when illness appears, it is also an opportunity for us to look back at ourselves.
Each Bacteria Has Its Own "Food"
Thầy Chân Quang explained that different bacteria have different preferences. The H5N1 bird flu virus likes to feed on the spinal cord, leaving patients paralyzed. The HIV virus attacks the immune system, robbing the body of its ability to defend itself. Each kind of illness is a reminder of humanity's mistaken ways of living.
People use this example: if a country has a strong army, it does not fear foreign invaders. But HIV strikes at the ministry of defense, causing the nation to collapse from within.
The Environment That Creates Fierce Bacteria
Why do new kinds of bacteria appear? Thầy affirmed: "Because the environment suited to that species has become complete." And it is humanity itself that has created that environment by destroying nature.
It is humans who, acting as God, have created these fierce strains of bacteria by wrecking the natural environment.
Destroying forests, using chemicals, and even our habit of washing with soap all contribute to ruining the living environment of beneficial microorganisms.
Soap and a Harmful Misunderstanding
In the past, people used clay and ash for cleaning. Today, soap kills off bacteria completely, but when it flows down the drain, soapy water also kills the microorganisms that decompose waste in our rivers. The rivers therefore turn black and foul-smelling. This is the consequence of a mistaken idea: that all bacteria are harmful.
One small error leads far astray. And today it is the generations of our children and grandchildren who continue to bear the consequences of that mistaken way of thinking.
The Path Back to Nature
According to Thầy, the most effective way to treat illness is repentance, reciting the Buddha's name, and making prayers and vows for the living beings that have departed. But more deeply, we need to change our way of living: reduce the killing of animals, live in harmony with the environment, and keep the mind/heart pure and calm.
Let us see each illness as a teaching from a master. When facing bacteria, we do not need to panic; we need to practice calmly and transform body and mind. Spring is the season of hope, an occasion for us to correct ourselves.
Wishing all Buddhist practitioners a peaceful new year, with joyful hearts and healthy bodies.
