The Dharma Chakara Pravartana Sutta, meaning "Setting in Motion the Wheel of Dharma," is the record of the Buddha's first sermon delivered in the Deer Park at Sarnath after his enlightenment. In this sermon, the Buddha expounded the Four Noble Truths (suffering, the origin of suffering, the cessation of suffering, and the path to the cessation of suffering) and the Eight-fold Path (Right Understanding, Right Thought, Right Speech, Right Action, Right Livelihood, Right Effort, Right Mindfulness, and Right Concentration) as the way to attain Nirvana. Thus, the Eight-fold Path is the central theme of this foundational discourse.
