Turning the Wheel of Dhamma (Dhammacakkappavattana Sutta) is a central discourse in the Buddha?s teachings. It is the first full teaching that the newly Awakened One gave, and it sets out the four noble truths and the ?Middle Way? ? the teaching structure that is the heart of his Way of realization. You can read the discourse in Connected Discourses (Samyutta Nikaya 56).
