"The Milinda Pañha (lit. 'Questions of Milinda') is a Buddhist text which dates from sometime between 100 BCE and 200 CE. It purports to record a dialogue between the Buddhist sage Nāgasena, and the Indo-Greek king Menander I (Pali: Milinda) of Bactria, who reigned in the 2nd century BCE.
The Milinda Pañha is regarded as canonical in Burmese Buddhism, included as part of the book of Khuddaka Nikaya. An abridged version is included as part of Chinese Mahayana translations of the canon. The Milinda Pañha is not regarded as canonical by Thai or Sri Lankan Buddhism, however, despite the surviving Theravāda text being in Sinhalese script.
The Chinese text titled the Monk Nāgasena Sutra corresponds to the first three chapters of the Milindapanha. It was translated sometime during the Eastern Jin dynasty (317–420)."
