Buddhism is a religion that began 2,500 years ago with Siddhartha Gotama, who became the Buddha after attaining enlightenment, and it now encompasses about 300 million followers worldwide. The core teachings revolve around the Four Noble Truths and the Eightfold Path, which provide guidance on overcoming suffering and achieving true happiness through self-awareness, ethical conduct, and compassion. Buddhism promotes tolerance of other beliefs, emphasizes the importance of understanding over faith, and invites individual exploration of its teachings.
