Among the Buddha’s many followers, ten were outstanding. Each was famous for possessing a particular talent which excelled all others. For example, Sariputra was the wisest; Maha-Kasyapa was known for his good practices; Maha-Maudgalyayana was famed for his supernatural powers; Purna was the best preacher, distinguished for his eloquence. This meant that he was more than just a master of rhetoric and silvery words; he could preach with such clarity that through him people could understand the Buddha’s deep teachings, and free themselves from sufferings.
