Pay Off Karma, Create Merit, Practice the Path
A teaching by Venerable Thich Chan Quang offers a new perspective on the law of cause and effect (karmic law). It is not superstition, but a foundational axiom of the universe that helps us live virtuously and peacefully.

Have you ever asked yourself, "Why do I do good deeds yet still encounter misfortune? Or why do some people live wickedly yet remain wealthy?" This question has surely touched the mind of many of us at least once. Today, please listen to a dharma talk by Venerable Thich Chan Quang. You will see that the law of cause and effect (karmic law), which many consider profound, is actually very close to home and serves as the foundation for a peaceful life.
Cause and Effect – The Axiom of the Universe
When mentioning cause and effect (karmic law), many immediately think of "you reap what you sow," a belief deeply ingrained in the Vietnamese consciousness. However, few realize that this is an axiom—a truth that requires no proof, much like in mathematics. Venerable Chan Quang begins with a scientific example. He states that all things proven by science must begin with an unprovable axiom.
Buddhists accept the law of cause and effect (karmic law) as such an axiom. This provides a solid foundation for living virtuously and avoiding evil, without needing to wait for scientific evidence.
Science Also Begins with Axioms
The teacher explains clearly: If no one accepted the axiom that "two parallel lines never intersect," geometry would never have come into existence. Similarly, Buddhism relies on the axiom of the law of cause and effect (karmic law). This does not contradict science; it simply exists at a level that science has not yet reached. As he says, science consists of logical, reasonable facts that can be proven both theoretically and experimentally.
Therefore, when someone claims that cause and effect (karmic law) is unscientific, we can confidently reply that every system of knowledge requires a starting point that cannot itself be proven.
Cause and Effect in the Buddha's Teachings (Dharma): Retribution of Suffering and Joy
However, cause and effect (karmic law) is not merely a physical or agricultural rule. In Buddhism, it is closely linked to the feelings of suffering (dukkha) and joy experienced by sentient beings. The teacher analyzes this point: Whenever we cause suffering (dukkha) to others, we incur sin and karma. When we bring happiness and joy to others, we receive blessings from merit.
This means that every word and action we take plants seeds of suffering (dukkha) or happiness in others, and we ourselves will reap corresponding karmic results.
Understanding Cause and Effect Leads to Subtle Living
When one deeply understands the law of cause and effect (karmic law), their behavior changes naturally. Without being taught, they instinctively act with politeness and subtlety. The teacher shares a story about young volunteers at a temple welcoming Buddhists.
He describes how young men standing at the door, seeing someone hesitating while looking at the temple map, would warmly invite them inside. They offered seats with the same care and precision as staff in a luxury hotel. Why did they behave this way? Not because they were trained, but because of their understanding of cause and effect (karmic law).
From this understanding, they became refined in every glance, smile, and word. They looked at everyone with love and spoke only with kind words, knowing that everything is part of the web of causes and effects.
How to Live with Cause and Effect Every Day?
The teacher advises each Buddhist to weigh good and evil in every thought, word, and deed. If a spoken word seems likely to create negative karma, stop immediately. If an action creates merit, do it right away. This is the principle of living:
In every word, every calculation, every plan, and every task, there should never be a single moment where our thinking departs from the awareness of the law of cause and effect (karmic law).
When practiced this way, life becomes precise, ethical, and filled with peace and joy.
Dear friend, the law of cause and effect (karmic law) is not an abstract philosophy. It is a compass that guides us through life without losing our way. Let every breath, every step, and every word be a seed of goodness. As the teacher said, "Pay off karma, create merit, practice the path." Trust in this and keep walking. Once cause and effect (karmic law) permeates your soul, sweet fruits will naturally arrive in their proper season.
