The document discusses the origins and key teachings of Buddhism. It states that Buddhism was founded by Siddhartha Gautama, who became known as the Buddha or "Enlightened One." As a prince, he was sheltered but witnessed suffering in the world, which led him on a spiritual quest. He achieved enlightenment and taught the Four Noble Truths and Eightfold Path to end suffering. His teachings spread across Asia through missionaries and traders along the Silk Road.
