Shortly after attaining Enlightenment, the Buddha travelled to the Deer Park in Isipatana near Varanasi and delivered his first sermon, the Dhammacakkappavattana Sutta: The Discourse on Setting the Wheel of Dhamma in Motion. During the discourse the Buddha gave an exposition of the Four Noble Truths (Pali: cattāri ariyasaccāni), the first of many during his forty-five year ministry. The Four Noble Truths are the foundation of the Buddha’s Teaching and are central to all schools of Buddhism.
