Siddhartha sat at the bottom of the Bodhi tree. He made a promise to keep meditating until he was enlightened. For forty days Devaputra Mara, the leader of demons, tried to stop Siddhartha. He made Siddhartha think of scary things. He made demons try to hurt Siddhartha with spears, arrows, fire, and rocks. Siddhartha did not fear them and kept his mind relaxed and the hurtful things became like flowers and many coloured lights. From Sila (morality), Samadhi (concentration), and Prajna (insight; wisdom), he became enlightened. After he was enlightened, he taught people about what he had learned for 45 years. He died when he was 80 years old.
