Cattāri Brahmavihārā

Today is the uposatha day that commemorates the first exposition of the Dhamma (the Dhammacakkappavattana Sutta) to the five ascetics and the entry into the stream of Kondañña. In addition to taking the precepts, it’s customary to chant the sutta. Here’s the text in English and Pali: http://www.ancient-buddhist-texts.net/Texts-and-Translations/Short-Pieces/Dhammacakkappavattanasuttam.pdf
