Sarpir-maá¹Âá¸Âa (Sanskrit: ) was a type of dairy product, one of five stages of milk described in Hindu and Buddhist texts.
Buddhist texts including the Nirvana Sutra describe five stages of milk as an analogy to stages of purification of the spirit:
<blockquote>Milk yields curd; curd yields butter; butter yields sarpis; sarpis yields sarpir-maá¹Âá¸Âa; sarpir-maá¹Âá¸Âa is the best.</blockquote>
Sarpir-maá¹Âá¸Âa has been theorised to be the early form of ghee.
In Chinese Buddhist texts, sarpir-maá¹Âá¸Âa was translated to tÃÂhú (éÂÂéÂÂ). The entry for tÃÂhú in Compendium of Materia Medica (1578) quotes various references, the earliest of which was written in the 5th century Liu Song dynasty.
The word éÂÂé is pronounced daigo in Japan. The word has been used in Daigo Temple, Emperor Daigo and Emperor Go-Daigo (both of whom named after the temple), and the word daigo-mi (éÂÂéÂÂå³), which means a superb flavor.
According to The Japanese Dairy Association, Emperor Daigo encouraged the production of so (é ¥, the aforementioned návanëta and sarpÃÂs), daigo, and other cheese-like products during his reign in the 10th century.
