When Buddha was a young man, he left his house leaving his luxurious life in search of knowledge. He wandered for several years meeting and holding discussions with other thinkers. He finally decided to find his own path to realisation, and meditated for days on end under a peepal tree at Bodh Gaya in Bihar, where he attained enlightenment. It was only after attaining that knowledge that he was known as the Buddha or the Wise One. He gave his first sermon at Sarnath, near Varanasi. For the rest of his life he travelled on foot went from place to place and taught people.
