Visperad
The Visperad is one of the texts in the Avesta collection. Its 24 chapters do not have any internal unity, but are only used within the Yasht i Visperad liturgy, where they are individually inserted into the text of the Yasna.
Name
The name of the text is based on Middle Persian wysplt', itself derived from Avestan vispe ratavo. It has been variously transliterated by scholars as Visperad, Vispered, Vispéred or Wisperad. The term itself has an ambiguous meaning. Subject to how ratu is translated, vispe ratavo may be translated as " all patrons", "all masters", or, the older and today less common, "all chiefs." or "all lords."Text
The text of the Visperad has no unity of its own, and is never recited separately from the Yasna. During the Visperad liturgy, its sections are not recited en bloc but are instead interleaved into the text of the Yasna. These supplementary sections are then – from a philological perspective – the passages that make up the Visperad. The standard abbreviation for Visperad chapter-verse pointers is Vr., though Vsp. may also appear in older sources.The Visperad itself exalts several texts of the Yasna, including the Ahuna Vairya and the Airyaman ishya, the Gathas, and the Yasna Haptanghaiti Unlike in a regular Yasna liturgy, the Yasna Haptanghaiti is recited a second time between the 4th and 5th Gatha.
Visperad liturgy
The text of the Visperad is used during the Visperad liturgy, also known in Middle Persian as Yasht i Visperad or Jesht-i Visperad. This means it is a Yasna liturgy, known in Middle Persian as Yasht, which includes a worship of all the ratus. The Visperad liturgy has a strong connection to yearly Zoroastrian festivals known as Gahambars, and it may have been created as an "extended service" for that occastion.As seasonal festivals, the gahambars are dedicated to the Amesha Spentas, the divinites that are in tradition identified with specific aspects of creation, and through whom Ahura Mazda realized creation. These "bounteous immortals" are the "all patrons" – the vispe ratavo – who apportion the bounty of creation. However, the Visperad liturgy itself is dedicated to Ahura Mazda, the ratūm berezem "high Master."
