Sariputra was the first among the Ten Great Disciples and the numerous other “hearers” and arhats who were personally assured by Sakyamuni of future Buddhahood. The congregation rejoiced to see that Sariputra was assured of his future Buddhahood, took off their outer robes, and offered them to the Buddha. (The monks, who had practically no possessions, were offering their only “luxury.” Wealthy followers made more costly offerings.) They venerated the Buddha and exalted him, saying, “The Buddha first turned the wheel of the law at Varanasi a long time ago. Now he turns the wheel of the unsurpassed and greatest law.”
