Fourth truth: path to the cessation of dukkha
The fourth noble truth is the path to the cessation of dukkha. This path is called the Noble Eightfold Path, and it is considered to be the essence of Buddhist practice.
The eightfold path consists of: Right Understanding, Right Thought,
Right Speech, Right Action, Right Livelihood, Right Effort, Right
Mindfulness, and Right Concentration.
While the first three truths are primarily concerned with
understanding the nature of dukkha (suffering, anxiety, stress) and its
causes, the fourth truth presents a practical method for overcoming
dukkha.
The path consists of a set of eight interconnected factors or
conditions, that when developed together, lead to the cessation of
dukkha. Ajahn Sucitto describes the path as "a mandala of interconnected factors that support and moderate each other."
Thus, the eight items of the path are not to be understood as stages,
in which each stage is completed before moving on to the next. Rather,
they are to be understood as eight significant dimensions of one's
behaviour—mental, spoken, and bodily—that operate in dependence on one
another; taken together, they define a complete path, or way of living.
