Buddhism, a religion with around 300 million followers worldwide, originated 2,500 years ago when Siddhartha Gotama, known as the Buddha, achieved enlightenment. It offers a purpose to life, a code of practice leading to true happiness, and teaches the Four Noble Truths and the Noble Eightfold Path, emphasizing that suffering can be understood and overcome. The teachings promote tolerance towards other beliefs and encourage individual exploration and understanding of one's own experiences.
