The fourth book of the Khuddaka Nikáya, containing 110 suttas, each of which begins with the words: vuttam h'etam Bhagavatá.
According to Dhammapála (ItA.24ff), the suttas were preached from time to time by the Buddha to Khujjuttará at Kosambí. She then repeated them to the five hundred women of Udena's palace, chief of whom was Sámávatí. In order to emphasise to her audience the fact that she was reporting the Buddha's words and not her own, she prefaced each sutta with the phrase quoted above. There was no need to describe any special circumstances in which the suttas were preached, because they were familiar to Khujjuttará's audience.
At the Rájagaha Council, Ananda repeated the suttas to the Assembly and they were gathered into this collection.
Itivuttaka is also the name given to one of the nine divisions (anga) into which the Buddha's preaching is divided and it is defined as follows: vuttam h'etam Bhagavatá ti ádinayappavattá dasuttarasatam suttantá Itivuttakam ti veditabbam (DA.i.24).
In the scholiast of the Kummásapinda Játaka (J.iii.409; l.21)), the Itivuttaka is mentioned in the plural (Itivuttakesu) and a sutta is quoted from it, extolling the virtues of generosity. Perhaps, the Itivuttaka was compiled as a result of a critical study of the authentic teachings of the Buddha, considered in a certain light and made for a specific purpose.
