Chance and Certainty: Are Those "Coincidences" Truly Random?
A dharma talk by Venerable Thích Chân Quang opens our awareness: every coincidence has its causes and conditions. Even fleeting thoughts can profoundly shape our lives.

Have you ever wondered whether today's meeting was mere chance or something destined? Some things happen beyond our expectations, but are they truly "coincidences"? In the dharma talk "Chance and Certainty," Venerable Thích Chân Quang helps us look deeply into the nature of the unexpected events in our lives.
Chance and certainty: two sides of one coin
We tend to think that chance refers to things we did not plan, while certainty refers to things we can arrange and predict. In truth, the boundary between them is very fragile.
For example, going to the temple today is certain because we arranged it in advance. Yet during the ceremony, running into an old friend might seem like chance. However, for that friend, meeting us may have been certain, because they had long wished for it. Venerable Chân Quang shares:
"Chance refers to things that happen which we did not anticipate, did not predict, did not arrange in advance. Certainty refers to things that happen which we can predict, arrange, and plan for in advance." (Venerable Thích Chân Quang)
So what truly decides? It is the conditions (dependent origination) — the karmic connections we have sown over countless lifetimes.
Nothing is purely random
Passing along a broken road, we suddenly have the thought to repair it. It seems like chance, but in fact it is the fruit of a kind and wholesome heart, cultivated over a long time. Venerable Chân Quang explains:
"What we see as certain is actually chance. And what we see as chance is actually the certainty of something else." (Venerable Thích Chân Quang)
Only someone with a heart of compassion would think of repairing the road. Someone without such a heart could pass by a thousand times and never notice. Thus, that "chance" is in fact the certainty of a long process of spiritual practice.
Fleeting thoughts: seeds of karma
The most frightening thing is not unexpected events, but the fleeting thoughts that arise in our minds. You might see a man being rude to his wife, and a thought flashes up: "If you cross me, I'll knock your teeth out." It is only a passing thought, yet it can become karma later on.
Venerable Chân Quang tells a story in the talk: A man eating at a food stall saw a husband scolding his wife, and felt the impulse to strike him. Thirty years later, they happened to meet again. The man felt such sudden hatred at the sight of him that he struck him without knowing why. It turned out to be a thought sown many lifetimes before. From this, the Venerable warns:
"Be careful with your random thoughts. You never know what may come of them later." (Venerable Thích Chân Quang)
Thoughts that seem random and harmless are recorded in the stream of karma, and can create great upheavals in the future. For this reason, practitioners must always remain awake and watch over their minds.
How can we control our random thoughts?
Venerable Chân Quang uses the image of a computer to illustrate. When you press a key, even if you delete it, the trace remains in the machine's memory. The mind is the same. An unwholesome thought, even after we ask for it to be erased, still remains. So what should we do?
"What does a practitioner, someone who knows the way, fear the most? They fear the random thoughts in their own mind, and they must bring those random thoughts under control." (Venerable Thích Chân Quang)
Control does not mean erasing thoughts after they arise, but preventing them from the start — through practice, through reciting the Buddha's name, and through keeping the mind pure. When our minds are filled with wholesome thoughts, unwholesome ones have no chance to arise.
A spiritual margin: leaving room for the unexpected
In life, there are events that fail despite our careful planning, because of unforeseen factors. The wisest people always leave a spiritual margin — that is, "knowing how to pray and ask for blessings and protection." Venerable Chân Quang says:
"Even the most experienced people always leave a spiritual margin. By praying, by asking the divine for protection, that person finds success more easily." (Venerable Thích Chân Quang)
Praying with sincerity not only brings us good fortune, but is also an act of humility, acknowledging our own limits. When we bow before the Buddha, we place our full trust in the protection of all the Buddhas, so that everything may unfold smoothly.
Conclusion: sow good seeds
Chance and certainty are always interwoven in life. Yet in truth, nothing is entirely random. Everything arises from our own minds. Let us keep our minds turned toward the good, for from a single fleeting wholesome thought, our whole life can change. Let us watch over our passing thoughts, and never forget to leave a spiritual margin for prayer. In this way, we will receive the very best in every circumstance. Homage to our Original Teacher, Shakyamuni Buddha.
