Having opened the hearts of his five companions with his teaching of the middle way, the Buddha now teaches the four truths of the noble ones (cattāro ariya-saccāni). These are: dukkha; its arising; its cessation; and the path leading to its cessation. This discourse centres on dukkha and craving (taṇhā), because the Buddha is concerned here with what coloured his own practice before his awakening – his sense of drivenness, of trying to get in the future something missing now.
