The last book of the Vinaya Piṭaka.
It is a digest of the other parts of the Vinaya and consists of nineteen chapters. The colophon states that the book was the work of a monk named Dīpa, probably of Sri Lanka.
The Commentaries (e.g., DA.i.17; Sp.i.18), however, speak of the Soḷasa Parivāra as having formed part of the Vinaya when it was rehearsed at the First Council. Perhaps the Parivāra corresponds to the mātikā of the Abhidhamma and was enlarged later on.
