The Visperad (from vîspe ratavo, "(prayer to) all patrons") is a collection of supplements to the Yasna. The Visparad is subdivided into 23 or 24 kardo (sections) that are interleaved into the Yasna during a Visperad service (which is an extended Yasna service).
The Visperad collection has no unity of its own, and is never recited separately from the Yasna
