According to tradition, Menander embraced the Buddhist faith, as described in the Milinda Panha, a classical Pali Buddhist text on the discussions between Milinda and the Buddhist sage Ngasena. He is described as constantly accompanied by a guard of 500 Greek ("Yonaka") soldiers, and two of his counsellors are named Demetrius and Antiochus. This type of discussion was known to ancient Greeks as a "sozo", it is important for Buddhists to understand the cultural context in which this discussion was held. (from wikipedia.com)
