Four Noble Truths

The content of the first sermon delivered by the Buddha to the five ascetic monks after he attained enlightenment, marking the beginning of the turning of the dhamma wheel.  The four noble truths are the truths of suffering (P: dukkha sacca, S: duhkha-satya, V: khổ đế), origin of suffering (P: samudaya sacca, S: samudhaya-satya, V: tập đế), cessation of suffering (P: nirodha sacca, S: nirodha-satya, V: diệt đế), and path to cease suffering (P: magga sacca, S: marga-satya, V: đạo đế).  The path to cease suffering is the Noble Eightfold Path.
