After his enlightenment
He assumed the title Lord Buddha (one who has awakened; the one who has attained enlightenment by himself). His name is pronounced differently in various countries. In the West, it is often pronounced "Boo-duh;" in India: "Boo-the" with the stress on the "th."
For seven days, he puzzled over his future: whether to withdraw from the world and live a life of seclusion, or whether to reenter the world and teach his Middle Way. He decided on the latter course: to proclaim his Dharma (teachings) to other humans so that they could also attain enlightenment.
He located five of his fellow seekers with whom he had earlier fasted, and rejoined them near Benares. They quickly became aware of the changes brought about by his enlightenment. It was to them that he preached his first sermon. It contained the essential teachings of Buddhism. All five accepted his teachings and were ordained as monks. After the Buddha's second sermon, all five achieved enlightenment. They are referred to as Arhants (saints).
