Grammatical Analysis
Udāna: [nt.] Inspired utterance; joyful exclamation. Derived from udāneti (to breathe out, to express joyfully).
Orthodox Definition
The Udāna is the third book of the Khuddaka Nikāya. It is a highly revered collection consisting of 80 short discourses.
Unlike standard suttas where the Buddha preaches in response to a question or to instruct the monks, an Udāna represents a specific psychological phenomenon. The commentaries explain that when the Buddha witnessed something profoundly moving—such as the total peace of an Arahat, the tragic blindness of worldlings, or the absolute security of Nibbāna—a wave of deep spiritual joy (pīti) would well up within him, overflowing into a spontaneous, poetic exclamation.
Each sutta contains a prose backstory detailing the event, culminating in the Buddha breathing forth the Udāna verse.
