Explanation:

The Setting in Motion of the Wheel of the Dharma Sutra or Promulgation of the Law Sutra is considered to be a record of the first teaching given by Gautama Buddha after he attained enlightenment. According to tradition, the Buddha gave this teaching in Sarnath, India, to the "five ascetics", his former companions with whom he had spent six years practicing austerities. The main topic of this sutra is the Four Noble Truths, which are the central teachings of Buddhism that provide a unifying theme, or conceptual framework, for all of Buddhist thought. This sutra also introduces the Buddhist concepts of the Middle Way, impermanence, and dependent origination.
