The Buddha taught four truths.
The first truth is called dukkha. This is often called suffering. It means that life can be painful or not at ease. This happens because nothing lasts forever. The second truth is the cause of this pain. It is called samudaya. This happens because of craving. It is a strong desire or longing for things.
The third truth is called nirodha. It says we can end this pain. We do this by letting go of our cravings. This brings a state called nirvana. In nirvana, the cycle of rebirth ends. 
The fourth truth is the way to reach this peace. It is called marga. This is the Noble Eightfold Path. It is a set of steps to follow. People use it to practice mindfulness and meditation. These truths help people understand how to find true freedom.
The Four Noble Truths are a very important set of ideas in Buddhism.
These truths work like a step-by-step way to understand life. The first truth is dukkha, which is often called suffering. It means things can feel unstable or not at ease. This happens because nothing stays the same forever. The second truth is samudaya, which is the cause of this pain. This cause is craving or a strong longing for things. The third truth is nirodha, which means we can end this craving. The fourth truth is marga, which is the path to reach that end. 
History tells us these truths are linked to the Buddha's first sermon. This sermon is called the Dhammacakkappavattana Sutta. It means "Setting the Wheel of Dhamma in Motion." The Buddha gave these teachings after he reached full awakening. Some scholars think this sermon was named as his first later on. Others believe the truths might have been added to the text later. Even so, they are a central part of many Buddhist stories.
There are many specific details about these truths in old texts. The Pali Canon is a large collection of these scriptures. In the Theravada tradition, these truths became very central by the 5th century CE. This tradition believes that understanding these truths can lead to liberation. The Mahayana tradition looks at them in a different way. They use the truths to explain how a liberated person still works in the world.
These ideas connect to how people practice mindfulness and meditation today. The fourth truth leads to the Noble Eightfold Path. This path helps people practice discipline and wholesome states. By following it, people try to reach nirvana. Nirvana is a state where craving stops and the cycle of rebirth ends. This helps people move away from the cycle of attraction and rejection. It is a way to find true peace and freedom.
The Four Noble Truths, known in Pali as ariya sacca, are a foundational conceptual framework in Buddhism.
The mechanism of these truths describes a specific causal chain. It begins with dukkha, which is often translated as suffering. This term comes from dush-stha, meaning "standing unstable." It refers to the unsatisfactory nature of transient existence where nothing is permanent. The second step is samudaya, the origin or cause of this instability. This is associated with craving, longing, or attachment to a transient world. The third step is nirodha, which is the cessation or ending of this craving. By letting go of attachment, the cycle of pain can be contained. The final step is marga, the path that leads to this cessation. 
There are different ways these truths are categorized in ancient texts. One common version is the full set found in the Dhammacakkappavattana Sutta. This text is titled "Setting the Wheel of Dhamma in Motion." Another version is a mnemonic set intended to help listeners remember the core ideas. This shorter set uses terms like "dukkham, samudayo, nirodha, marga." The truths can also be framed differently depending on the subject. Some versions focus on the arising of the world or the arising of the āsavas. These variations all point toward the same basic Buddhist orientation regarding impermanence and desire.
History shows that the role of these truths has evolved over time. They are traditionally identified as the first teaching given by the Buddha after his awakening. However, some scholars, such as L.S. Cousins and Carol S. Anderson, suggest this identification might have happened later. They note that the truths may have been added to the first sermon in some versions. By the 5th century CE, the truths became central to the Theravada tradition. This tradition holds that gaining insight into these truths is liberating in itself. This happened as "prajna," or liberating insight, became a prominent part of Buddhist practice.
The significance of these truths varies between different Buddhist traditions. In the Theravada tradition, insight into the truths is a primary goal for liberation. In the Mahayana tradition, the truths are less prominent as a central focus. Mahayana practitioners often prioritize insight into sunyata, or emptiness, and the Bodhisattva path. However, Mahayana thinkers reinterpreted the four truths to explain how a liberated being remains operative in the world. In the West, the truths gained even more prominence during the 19th century. This was due to the exploration of Buddhism by Western colonialists and the rise of Buddhist modernism.
Specific details regarding the terms provide deeper meaning to the philosophy. For example, the term dukkha is described by some as being the opposite of sukha, or non-transient pleasure. It describes the insecurity of all conditioned phenomena. The term samudaya relates to the "rising" or "coming together" of constituent elements. The goal of the path is to reach nirvana, which is the cessation of craving. When craving stops, the cycle of rebirth, known as samsara, no longer arises. This process involves reversing a causal chain where sensation leads to craving, which leads to karma, which leads to rebirth.
These truths connect to broader systems of thought regarding the mind and existence. They relate to the five skandhas, which are the components of a being. Sensory contact leads to sensations and perceptions, which are then interpreted by saṅkhāras, or inclinations. This cycle can lead to the twelve nidānas, a process describing how craving leads to becoming and birth. In some interpretations, such as in Thai Buddhism, this describes the repeated birth of the ego-mind.
