Sarnath is a place near Varanasi in Uttar Pradesh, India. It is one of the four most important Buddhist pilgrimage sites, along with Lumbini, Bodh Gaya, and Kushinagar.

This sermon is known as the Dhammacakkappavattana Sutta, or the Discourse on Setting in Motion the Wheel of the Law. In this sermon, Buddha taught the Four Noble Truths, which are the foundation of his teachings:

3. Nirodha: Suffering can be ended.
4. Magga: The path to the end of suffering is the Noble Eightfold Path.
