Udāna - Inspired Utterances (of the Buddha)
80 suttas, across 8 chapters, each with 10 discourses. Each discourse includes a prose portion followed by a verse.
In the Bodhivagga Sutta are recorded the first words spoken aloud by the newly enlightened Buddha:
"yadā have pātubhavanti dhammā, ātāpino jhāyato brāhmaṇassa
athassa kaṅkhā vapayanti sabbā, yato pajānāti sahetu dhammā"
"When the true nature of things becomes clear to the ardent, meditating recluse, then all their doubts fade away, since they realise that everything has to have a cause."
