This chant, in English, is for the day of Asalha Puja, July 5, the full moon day (2020). Asalha Puja commemorates the first teaching of the Buddha, The Discourse of Setting the Wheel of Dhamma in Motion, the Dhamma-cakkappavattana Sutta.

On this day the Buddha taught the group of five ascetics, and Anya Kondanya became the first disciple to see the Dhamma.
