Upāli
Appearance
Upali (Sanskrit उपालि upāli) was a monk in the order of Buddha. Before joining the order, its interesting to note he worked as a barber. He asked if a person of "low birth" such as he could join the order, Buddha on purpose ordained him before the princes and asked the princes to pay homage to Upali, who by then had become an Arhant with Buddha's sermons while Buddha was getting a hair cut. He became the Chief disciple in knowing the rules of the order.
