First Turning of the Wheel of Dharma - Chökhor Düchen
The 4th of the 6th month, the "First Turning of the Wheel of Dharma" (first teaching) is celebrated. For the first seven weeks after his Enlightenment, Buddha did not teach.

Encouraged by Indra and Brahma, he then gave his first teachings at Sarnath on the Four Noble Truths, which forms the basis of the Buddhist teachings.
