The Lord Buddha gave them his FIRST SERMON called "Dhamma-cakkappavattana Sutta" or the Discourse on Setting the Wheel of Dhamma in Motion. Not long after that, the head of the Five Ascetics, named "Kondanna" got "The Eye of Dhamma" and asked for ordination from The Lord Buddha. He became the FIRST MONK in Buddhism. The full moon day of the eighth lunar month became the day that honored the Sangha, or the community of the monks.
