The four dharma seals are four truths that are present in every Buddhist teaching. They serve as a ‘seal of approval’ because any teaching which contradicts one or more of these seals is not authentic dharma. Also, understanding the four seals of Buddhism ‘seals’ our practice. Once we fully recognize the truth of these four, they cannot be forgotten. The four seals inform our understanding of reality and illuminate the path to living a joyful, contented life.
